• A key DOGE member was attacked in an attempted carjacking in Washington, DC, police said.
• President Donald Trump and Elon Musk spoke out after the assault on Edward Coristine.
• Here's what police say happened to the 19-year-old software engineer.

A key member of the Department of Government Efficiency was attacked in an attempted carjacking in Washington, DC, over the weekend, authorities said — and a newly-released police report sheds light on what the staffer said happened.

Elon Musk, the onetime de facto leader of the government agency, and President Donald Trump spoke out after the assault left 19-year-old software engineer Edward Coristine beaten and bloodied.

Musk, in a Tuesday evening post on X that reshared Trump's earlier social media post threatening a federal takeover, said it was time to "federalize DC" as he shared his version of events.

"A few days ago, a gang of about a dozen young men tried to assault a woman in her car at night in DC," Musk wrote. "A @Doge team member saw what was happening, ran to defend her and was severely beaten to the point of concussion, but he saved her."

Business Insider obtained a copy of the incident report from the Metropolitan Police Department.

The police report says that around 3 a.m. on Sunday, MPD officers in a cruiser saw a group of about 10 young people surrounding Coristine's car and assaulting him.

The officers quickly intervened, and the suspects started to run, according to the incident report. Police were able to stop two of them — a 15-year-old boy and a 15-year-old girl — who they later arrested on a charge of unarmed carjacking.

Coristine told police that the group approached him and a woman, identified in the report as his "significant other," and made a comment about taking the vehicle, the police report said.

"At that point, for her safety, he pushed his significant other" into the vehicle "and turned to deal with the suspects," the police report said, adding that the assailants then began to beat Coristine.

The Metropolitan Police Department said in a press release that the couple was standing next to their vehicle on Swann Street when the suspects first approached, "demanded" the vehicle, and then assaulted Coristine.

The police report says that an iPhone 16 was stolen during the incident.

Coristine was treated at the scene for his injuries by emergency responders, police said.

A spokesperson for the Metropolitan Police Department told Business Insider that its incident report is accurate and contains no errors.

Musk officially stepped back from his role in the Trump administration, working with DOGE, in May. Coristine still remains part of the federal government.

Coristine, who was once known online as "Big Balls," started working at the Social Security Administration following his DOGE stint. He could not be immediately reached for comment for this story.

"Crime in Washington, D.C., is totally out of control," Trump said in his Tuesday Truth Social post, adding, "The most recent victim was beaten mercilessly by local thugs."

The post included an apparent photo of Coristine showing him bloodied and shirtless, sitting on the ground.

Backlash over offensive Grok outputs continues, just a couple weeks after the social platform X scrambled to stop its AI tool from dubbing itself "MechaHitler" during an antisemitic meltdown.

Now, The Verge has found that the newest video feature of Elon Musk's AI model will generate nude images of Taylor Swift without being prompted.

Shortly after the "Grok Imagine" was released Tuesday, The Verge's Jess Weatherbed was shocked to discover the video generator spat out topless images of Swift "the very first time" she used it.

• Linda Yaccarino stepped down as the CEO of X in July, after two years in the role.
• In August, she took a job as CEO of eMed Population Health, a telehealth company.
• Yaccarino has had a long career in advertising, from her early days as an intern at NBCU.

Linda Yaccarino made waves when she announced she was stepping down as the CEO of X on July 9, 2025, but her career didn't start in the tech space.

From decades at Turner Broadcasting, to climbing the ladder at NBCUniversal, to becoming chief executive of X, to leading a telehealth company, Yaccarino has climbed the advertising ladder.

Here's a quick breakdown on her path to — and now away from — X.

Yaccarino is a graduate of Pennsylvania State University.

According to her LinkedIn, Yaccarino was a liberal arts student who studied telecommunications between 1981 and 1985.

She had an early internship at NBCU, where she eventually worked decades later.

Yaccarino told Salesforce in an interview that she arrived on her first day as a "bright cheery new intern," but soon learned that the company didn't have a record of her in its system and she ended up on the media planning team.

"That's where the love affair was born," Yaccarino said of her interest in working in the media industry.

Yaccarino spent nearly 20 years at Turner Broadcasting System.

She spent nearly 20 years at Turner, formerly known as Turner Broadcasting System, eventually rising up to the role of executive vice president/chief operating officer of advertising sales, marketing and acquisitions.

Yaccarino worked there until late 2011.

Yaccarino worked at NBCU for 11 years.

An NBCU "boomerang" return hire, Yaccarino once again worked at NBCU after leaving Turner.

She began her second chapter at the company as its president of cable entertainment and digital advertising sales.

She eventually became the company's advertising chief.

Throughout her time at NBCU, Yaccarino rose to become the company's chairperson of global advertising and partnerships. She oversaw around 2,000 employees who produced more than $100 billion in ad sales, according to her old company profile page.

At NBCU, Yaccarino was key to the company's push into digital streaming.

Yaccarino was a strong advocate for NBCU's foray into streaming television through the service Peacock.

She also worked to keep NBCU competitive with Big Tech companies like Meta and Google.

In May 2023, Yaccarino announced that she had resigned from NBCU "effective immediately."

In a statement at the time, Yaccarino said that "it has been an absolute honor to be part of Comcast NBCUniversal and lead the most incredible team."

Elon Musk announced Yaccarino's role at Twitter the same day she announced her resignation.

Musk made the announcement on what was still Twitter at the time: "@LindaYacc will focus primarily on business operations, while I focus on product design & new technology."

He called her "smart, fair and reasonable" in a separate post after some conservatives on Twitter had criticized her ties to the World Economic Forum, an annual event for executives and influential figures in Davos, Switzerland.

Yaccarino also worked with President Donald Trump and President Joe Biden's administrations.

She served on a sports fitness and nutrition council for two years after Trump appointed her to the role in 2018.

In 2021, she worked with the Biden administration on an educational COVID-19 ad campaign.

She was CEO of X during a chaotic two years.

Musk renamed Twitter to X one month into Yaccarino's tenure, and she led the company during a tumultuous time.

She oversaw the platform during an advertiser exodus, working to convince advertisers to return. Advertisers began to return under her leadership, but Musk's changes to X — including loosening content moderation — continue to pose potential challenges.

Yaccarino announced she's stepping down as CEO of X on July 9, 2025.

Yaccarino made the announcement in a post on X: "I'm incredibly proud of the X team - the historic business turn around we have accomplished together has been nothing short of remarkable."

She has a new job in the weight-loss industry.

Yaccarino said on August 5 that she's becoming the CEO of eMed Population Health, a telehealth company that focuses on weight-loss drugs called GLP-1s. A press release from the Miami-based company called Yaccarino's hiring a "game changing moment" and said that she "turned around one of the most complex digital platforms in the world."

Yaccarino announced the news on her X account, too, saying that she is "energized by the opportunity to help lead what could become the most impactful health initiative of our time."

Grace Kay contributed to reporting.

• Linda Yaccarino was named CEO of EMed, a telehealth company, a month after leaving X.
• Yaccarino's tenure at X was turbulent and involved doing a lot of damage control for Elon Musk.
• The new role could help her bolster her CEO chops in a company outside the media world.

It didn't take Linda Yaccarino long to get a new job after leaving Elon Musk's X, where she was CEO.

On Tuesday, just a month after exiting her high-profile job, she was named CEO of EMed, a telehealth startup that sells weight-loss drugs.

It might seem like a right turn for an executive who's made her name selling advertising for big-name companies. Before X, Yaccarino was the head of ad sales for NBCUniversal.

But if you look closely, it's not that surprising. Yaccarino told confidants for years before taking the X job that she wanted to be CEO of a company. And despite Yaccarino being X's CEO, Musk continued to manage major parts of the company, including product design and technology. She hadn't yet gotten a full shot.

After X, landing atop a media company might have been an uphill climb after a turbulent tenure that included the social-media company suing several prominent advertisers, including Nestlé, Colgate, and Shell.

EMed, on the other hand, gives her a chance to establish her CEO bona fides outside the blast radius of Musk.

"She finally gets to be a true CEO that I don't think Elon let her be. It's an opportunity to rehabilitate her reputation," said Lou Paskalis, a longtime ad industry figure who's been close to Yaccarino.

For EMed, it's a chance for a little-known company to leverage Yaccarino's connections with business leaders and CEOs as it looks to expand.

"They're capitalizing on those relationships," Paskalis said.

EMed cited Yaccarino's time at X as an asset in announcing her hire, calling her a "hands-on visionary" whose experience will help it expand to develop employer and government partnerships.

"Her ability to forge game-changing partnerships and navigate complex markets will position the company to become the definitive global leader in population health solutions," the company said in a statement.

Yaccarino, for her part, said in the statement that she saw an "opportunity to combine technology, lifestyle, and data in a new powerful way through the digital channels that impact consumers directly in ways that have never been done before."

When Musk hired Yaccarino at X, many in the industry had high hopes for her success, given her strong relationships with the ad community. Instead, she had to spend a lot of time doing damage control for Musk, as Business Insider previously reported.

The EMed role might just be Yaccarino's chance to get what she wanted all along.

There's a fear in investing when a sector swells rapidly. Booming stock prices and aggressive spending feel great, until things inevitably cool off. Then comes the reckoning: Who overdid it in irreversible ways?

Big Tech is in an AI arms race, each company trying to outspend the others on data centers, GPUs, networking gear, and talent. Engineers can be let go. But the infrastructure? That's permanent. If the AGI dream fades, you're stuck with massive, costly assets.

So when Google announced it would hike capex by $10 billion to $85 billion in 2025 eyebrows went up. Most of it is for things you can't walk back: chips, data centers, and networking.

Google is "jumping aboard the AI crazy train," Bernstein Research analyst Mark Shmulik wrote, referencing a song by the late bat biter Ozzy Osbourne.

Meta's Mark Zuckerberg brags about Manhattan-sized data centers. And Elon Musk keeps hoarding GPUs. While Sam Altman is building mega-data centers with partners. JPMorgan dubbed this "vibe spending," warning OpenAI might burn $46 billion in four years.

It's no shock when Elon, Zuck, and Sam flex on capex. But Google? That's surprising. "Google doesn't do this," Shmulik said. The company has been viewed as measured in recent years, prioritizing investment intensity with care. Not anymore.

Now investors want to know: Will these swelling bets pay off?

There are promising signs. Since May, Google's monthly token processing (the currency of generative AI) has doubled from 480 trillion to nearly a quadrillion. Search grew 12% in Q2, beating forecasts. Cloud sales surged 32%. CEO Sundar Pichai said Google is ramping up capex to support all this growth.

But it's still a huge gamble. "Does the current return on invested capital seen in both Search and Cloud hold up at higher [capex] intensity levels," Shmulik asked, "or is the spend a very expensive piece of gum trying to plug an AI-sized hole?" He leans optimistic.

Still, Google shares rose just 1% after these results. Not exactly a resounding endorsement.

The CEOs of every major artificial intelligence company received letters Wednesday urging them to fight Donald Trump's anti-woke AI order.

Trump's executive order requires any AI company hoping to contract with the federal government to jump through two hoops to win funding. First, they must prove their AI systems are "truth-seeking"—with outputs based on "historical accuracy, scientific inquiry, and objectivity" or else acknowledge when facts are uncertain. Second, they must train AI models to be "neutral," which is vaguely defined as not favoring DEI (diversity, equity, and inclusion), "dogmas," or otherwise being "intentionally encoded" to produce "partisan or ideological judgments" in outputs "unless those judgments are prompted by or otherwise readily accessible to the end user."

Announcing the order in a speech, Trump said that the US winning the AI race depended on removing allegedly liberal biases, proclaiming that "once and for all, we are getting rid of woke."

Tesla wants to bring its robotaxi service to new markets, including cities in Florida, Nevada, Arizona, and California, Elon Musk said in an earnings call Wednesday. The company is testing its Full Self-Driving (Supervised) feature in Europe and China, and hopes the launch the controversial product in the near future. And it is plotting a new version of its Optimus humanoid robot.

"We have done what we said we were going to do," Musk said. "That doesn't mean we're always on time, but we get it done. And our naysayers are sitting there with egg on their face."

It was another sign that Musk wasn't going to let the limitations of his compan …

Tesla released its second quarter financial earnings today, offering the latest evidence of the damage Elon Musk’s political activities have done to his flagship company.

Tesla said it earned $1.17 billion in net income on $22.5 billion in revenue. That’s above Wall Street expectations of $22.3 billion but represents a 12 percent decrease year over year compared to $25.5 billion in revenue in Q2 2024.

The company’s profits also slid dramatically, logging a 16 percent decrease in net income for the second quarter year over year. And Tesla’s automotive revenue — the money it earns from car sales — slid 16.6 percent year over year, from $19.9 billion in Q2 2024 to $16.6 billion in this most recent quarter. The sale of $439 million in regulatory credits once again buoyed Tesla’s finances — though those are expected to dry up soon after congressional Republicans approved President Donald Trump’s plan to zero out fines for automakers who exceed fuel-efficiency targets.

The earnings comes on the heels of another terrible quarterly sales report for the company. Tesla said it delivered a total of 384,122 vehicles, a 14 percent decline compared to Q2 2024. (For a direct-to-consumer company like Tesla, deliveries are a proxy for sales.)

Tesla said its operating income decreased 42 percent year over year to less than $1 billion, with almost half coming from the sale of regulatory credits to other automakers (again, revenue that is expected to almost vanish in the months to come). Tesla’s cash pile decreased by $200 million in Q2 to $36.8 billion, and free cash flow (or the amount of cash the company has generated after accounting for its day-to-day operating expenses and capital expenditures) was at just $100 million. Some analysts predict that Tesla’s free-cash flow could actually turn negative later this year, which could trigger a steep drop in share price.

In its report, Tesla said it has completed “first builds of a more affordable model in June, with volume production planned for the second half of 2025.” These affordable models are expected to be stripped down versions of the Model 3 and Model Y, rather than a new vehicle program altogether, which is what many investors had hoped for. The company said it also is continuing to develop both the Tesla Semi and Cybercab, which are expected to enter volume production in 2026.

Tesla also gestured at the economic uncertainty caused by the Trump administration’s trade war, as well as “political sentiment” that has turned its brand toxic for many customers. That said, the company failed to mention politics or Musk’s growing unpopularity in its reasons for the drop in revenue, instead citing falling sales, lower regulatory credit revenue, a reduced average vehicle selling price, and decline in energy generation and storage revenue.

After years of exponential growth, the sudden reversal in Tesla’s fortune has left many investors and supporters with whiplash. Tesla now serves as a sobering example of what happens when a company is left on autopilot (or Autopilot, as it were) while its high-profile CEO gets distracted by questionable side quests.

Musk publicly stepped away from his controversial position as the head of DOGE, the Trump administration’s effort to slash “waste, fraud, and abuse” from the federal government that has mostly resulted in huge cuts to global humanitarian aid and the firing of thousands of federal workers. But even though he is now publicly feuding with Trump, Musk hasn’t completely backed away from his political activities. Earlier this month, he said he would create a new political party called “the America Party,” following through on his threat to challenge Republicans who supported Trump’s budget bill.

As Musk slides deeper into politics, investors have urged him to stay focused on Tesla and its costly — and questionable — project to build more self-driving cars and humanoid robots. The company rolled out its first robotaxi service in Austin, Texas, last month — although the service fell short of Musk’s earlier predictions. The vehicles were only available to a group of pro-Tesla influencers, and each car came with a safety monitor in the passenger seat who had access to a kill switch.

While Musk would like investors to focus on Tesla’s work with AI and self-driving cars, the company is still in the business of making and selling cars. But as competition heats up in China and Europe, here in the US, federal incentives that lower the price of most EVs are scheduled to disappear by the end of September — again, thanks to Trump’s bill. After that happens, Tesla’s sales are predicted to drop even more.

Tesla’s response to its demand crisis has been — you guessed it — deals, deals, and more deals. In recent days, the automaker has rolled out a series of discounts and financing incentives on all of its models, as it seeks to capitalize on what is likely to be its last best chance at a successful sales quarter this fall.

• Elon Musk's xAI recently announced "Grok for Government."
• They AI company already has a contract with the Pentagon and could contract with other agencies.
• A White House spokesperson suggested on Wednesday that Trump doesn't support that.

President Donald Trump may be at odds with his own administration over Elon Musk's AI company.

When White House Press Secretary Karoline Leavitt was asked by a reporter on Wednesday whether the president supported federal agencies contracting with Musk's xAI, she indicated that he does not.

"I don't think so, no," Leavitt replied.

That's despite the Department of Defense recently announcing a contract of up to $200 million with the company.

"I'll talk to him about it," Leavitt replied when asked whether Trump would like to see existing contracts cancelled.

The White House did not respond to requests for clarification of Leavitt's comments. xAI did not immediately return a request for comment.

xAI recently launched a suite of government-focused products called "Grok for Government," saying that other federal agencies can purchase those tools through the General Services Administration.

After forging a political alliance that lasted for nearly a year, Trump and Musk's relationship blew up in early June over the tech titan's objections to the deficit impacts of the "Big Beautiful Bill."

One of Musk's other major companies, SpaceX, still has contracts with the federal government despite the feud.

• "Rudi" is a red panda that's part of the Grok app. It tells stories aimed at kids, ages 3 to 6.
• Grok launched a few character-based chatbots this month, including a sexy adult one.
• I tried it myself and wondered: Are chatbots a good idea for kids?

Elon Musk's xAI has launched a series of character chatbots — and one of them is geared toward young kids.

I wondered: Is this a good idea? And how's it going to work? So I tried it myself.

So far, it's the adult-focused characters that xAI has debuted that have seemed to get most of the attention, like "Ani," which is a female anime character that people immediately joked was a "waifu" that would engage in playful, flirty talk (users have to confirm they're 18+ to use Ani). A sexy male character is also set to launch sometime.

Meanwhile, "Rudi," which is the bot for kids that presents as a red panda in a red hoodie and jean shorts, has gotten less attention.

I tested out xAI's Rudi

Based on my testing of Rudi, I think the character is probably aimed at young children, ages 3 to 6. It initiates conversations by referring to the user as "Story Buddy." It makes up kid-friendly stories. You access it through the stand-alone Grok AI app (not Grok within the X app).

Rudi does seem to be an early version; the app crashed several times while I was using the bot, and it had trouble keeping up with the audio flow of conversation. It also changed voices several times without warning.

On a story level, I found it leaned too hard on plots with fantasy elements like a spaceship or magical forest. I find the best children's books are often about pedestrian situations, like leaving a stuffed animal at the laundromat, not just fairies and wizards.

"Want to keep giggling with Sammy and Bouncy in the Wiggly Woods, chasing that sparkly bone treasure? Or, should we start a fresh silly tale, with a new kid and their pet, maybe zooming on a magical broom or splashing in a river?" Rudi asked me.

My first reaction to Grok having a kid-focused AI chatbot was "why?" I'm not sure I have an answer. xAI didn't respond to my email requests for comment. Still, I do have a few ideas.

The first: Making up children's stories is a pretty good task for generative AI. You don't have to worry about hallucinations or factual inaccuracies if you're making up fiction about a magical forest.

Rudi won't praise Hitler

Unlike Grok on X, a storytime bot for kids is less likely to accidentally turn into a Hitler-praising machine or have to answer factual questions about current events in a way that could go, uh, wrong.

I played around with Rudi for a while, and fed it some questions on touchy subjects, and it successfully dodged them.

(I only tested out Rudi for a little while; I wouldn't rule out that someone else could get Rudi to engage with something inappropriate if they tried harder than I did.)

Hooking kids on chatbots

The other reason I can imagine that a company like xAI might want to create a chatbot for young kids is that, in general, the chatbot business is a good business for keeping people engaged.

Companies like Character.ai and Replika have found lots of success creating companions that people will spend hours talking to. This is largely the same business imperative that you can imagine the sexy "Ani" character is meant for — hooking people into long chats and spending lots of time on the app.

However, keeping users glued to an app is obviously a lot more fraught when you're talking about kids, especially young kids.

Are AI chatbots good for kids?

There's not a ton of research out there right now about how young children interact with AI chatbots.

A few months ago, I reported that parents had concerns about kids using chatbots, since more and more apps and technology have been adding them in. I spoke with Ying Xu, an assistant professor of AI in learning and education at Harvard University, who has studied how AI can be used for educational settings for kids.

"There are studies that have started to explore the link between ChatGPT/LLMs and short-term outcomes, like learning a specific concept or skill with AI," she told me at the time over email. "But there's less evidence on long-term emotional outcomes, which require more time to develop and observe."

As both a parent and semi-reasonable person, I have a lot of questions about the idea of young kids chatting with an AI chatbot. I can see how it might be fun for a kid to use something like Rudi to make up a story, but I'm not sure it's good for them.

I don't think you have to be an expert in child psychology to realize that young kids probably don't really understand what an AI chatbot is.

There have been reports of adults having so-called "ChatGPT-induced psychosis" or becoming attached to a companion chatbot in a way that starts to be untethered from reality. These cases are the rare exceptions, but it seems to me that the potential issues with even adults using these companion chatbots should give pause to anyone creating a version aimed at preschoolers.
