Introduction

In this episode of WSJ's "What’s News," host Alex Osola delves into several high-impact stories shaping the business and political landscape.

Federal Reserve’s Divided Stance and Jerome Powell's Leadership

At the outset (00:44), Osola introduces the emerging split within the Federal Reserve's rate-setting committee. Minutes from the latest meeting reveal that while a majority of officials anticipated the possibility of interest rate cuts later in the year, only two supported an immediate rate reduction. This division highlights differing perspectives on the appropriate monetary policy trajectory.

Discussion with Brian Schwartz: Osola engages with WSJ White House economic policy reporter Brian Schwartz (02:01). Schwartz explains, “He’s got officials in his camp, according to the latest minutes, that basically feel a mix of different things.” Powell is navigating the challenges of leading a divided committee while facing external pressure from President Trump, who is reportedly advocating for swift rate cuts and discussing potential successors for Powell.

Schwartz identifies two primary candidates for the next Fed Chair: Kevin Warsh, a former Fed board governor, and Kevin Hassett, the president’s National Economic Council director (02:51). He remarks, “They are two very different men as it pertains to their criticism of the Federal Reserve,” indicating how the choice of successor could signal a shift in Fed policies.

Linda Yaccarino’s Departure from X and Its Implications

Linda Yaccarino's resignation as CEO of X marks the end of a pivotal chapter for Elon Musk's social media platform. Osola explores the circumstances surrounding her departure with insights from WSJ advertising editor Suzanne Vernica (04:10).

Vernica explains, “Linda is stepping down. They're still not out of the woods in advertising. Spending isn't surging or anything. They’re expected to finally grow ad spending this year, but they're far from close to what they made pre-Elon takeover.” Yaccarino's tenure was marked by efforts to stabilize X’s advertising revenue amidst significant challenges, including advertiser hesitancy and a turbulent merger with Xai.

Yaccarino implemented strategies to enhance brand safety and attract advertisers by integrating more celebrity and sports content. Despite these efforts, ad spending remained sluggish compared to pre-acquisition levels. Her departure coincides with X's critical role in funding Elon Musk's ambitious push into artificial intelligence, underscoring the platform’s strategic importance within Musk’s broader business ventures.

Market Highlights: Nvidia’s $4 Trillion Valuation and Major Index Movements

The episode highlights significant movements in the stock market, with major US indexes closing higher (06:21). The Nasdaq reached a record high, up approximately 0.9%, the Dow Jones Industrial Average climbed about half a percent, and the S&P 500 increased by around 0.6%, maintaining proximity to its recent peak.

A standout story is Nvidia’s ascent to a $4 trillion market capitalization, making it the first company globally to achieve this milestone. Osola emphasizes the magnitude by noting, “If Nvidia were a country, it would rank as the fifth largest in the world, behind only the U.S., China, Germany, and Japan” (06:21). This achievement reflects Nvidia's pivotal role in the artificial intelligence and semiconductor industries. However, the stock slightly retreated from the $4 trillion mark by the end of the trading day.

Justice Department Investigates UnitedHealth Group’s Medicare Practices

Osola reports on the Justice Department's ongoing investigation into UnitedHealth Group’s Medicare billing practices (08:15), featuring insights from WSJ health care reporter Christopher Weaver.

Weaver details that prosecutors are scrutinizing how UnitedHealth allegedly employed medical professionals to record diagnoses that inflated Medicare payments. “They deployed doctors and nurses to gather diagnoses that bolstered its payments” (08:46). UnitedHealth initially denied any wrongdoing but has since acknowledged the investigation, stating they prefer to handle discussions directly rather than through the press. They have implemented third-party audits to oversee their diagnosis recording processes.

Weaver highlights that UnitedHealth's aggressive billing tactics surpass those of other major insurers, creating significant repercussions. “United engaged in these tactics in a much more aggressive way than many other major insurers” (10:22). This investigation signals a broader crackdown on Medicare billing practices, prompted in part by investigative reporting from the Journal.

---

Surge in Measles Cases in the United States

The episode concludes with an alarming public health update on measles (11:01). According to the CDC, the US has reported 1,288 measles cases by mid-2025, surpassing the 1,274 cases recorded in 2019 and marking the highest number in 33 years. Over 90% of the infected individuals were either unvaccinated or had unknown vaccination statuses.

The outbreak, which originated in West Texas, has led to hundreds of hospitalizations and the unfortunate occurrence of measles-related deaths for the first time in a decade. The resurgence of this vaccine-preventable disease underscores ongoing public health challenges and the critical importance of vaccination efforts.

United engaged in these tactics in a much more aggressive way than many other major insurers. And the reality is that some of those other companies have a lot less to lose than United has got.

[Alex Osola]

It's Wednesday, July 9th. I'm Alex Osola for the Wall Street Journal. This is the PM edition of what's news, the top headlines and business stories that move the world today. There's an emerging split inside the Federal Reserve's rate setting committee. At their meeting last month, a majority of Federal Reserve officials expected they would be able to resume interest rate cuts this year, but only two of them voiced support for a rate cut as soon as this month. That's according to the minutes from last month's meeting released today. With a customary three week lag, officials who believed lower rates would be appropriate later this year thought those moves could be justified by a weaker labor market or more modest and temporary inflation pressures from tariffs. But the minutes noted that a meaningful minority of officials thought inflation had not made enough progress towards the Fed's 2% goal to justify lowering rates. A divide among Fed officials is just one of the factors putting Fed Chair Jerome Powell in a tight spot. For more, I'm joined now by WSJ White House economic policy reporter Brian Schwartz. Brian, Jerome Powell seems to be in a bit of a bind, right? He has a divided Fed on one side, pressure from President Trump on the other side. How's he doing with all of this?

[Brian Schwartz]

Well, it's definitely pressure on the Fed chair. There's no debating that. He's got officials in his camp, according to the latest minutes, that basically feel a mix of different things. The reality is that that's going to put a lot of pressure on Powell to determine and lead the Fed board into making a decision in potentially the coming weeks by the end of the month. He's also dealing with something else. Is President Trump publicly taking aim at him and demanding effectively that he cuts rates. President may dispute that's what he's doing, but in reality that's the other pressure point that Powell faces is the fact is, is that the president is already talking to people who should replace him.

[Alex Osola]

Right. Let's talk about that sort of apprentice style contest for who is going to be replacing Powell as Fed chair. What do we know about the candidates and is one sort of edging out the other even at this relatively early stage?

[Brian Schwartz]

Well, the reporting we have now is that there's two Kevins is how we defined it. There's Kevin Warsh, former Fed board governor, and Kevin Hassett, the president's National Economic Council director. These are two people who really have a really good shot to becoming the next Fed chair. I'm not gonna say it's come down to those two, but they are in the top tier of considerations for the job. Kevin Hassett, longtime economist, longtime Trump loyalist Kevin Warsh, he's been hanging around the net trying to get a job in the Trump administration. Fed chair, treasury secretary, you name it. This dude's been around. So it's kind of an interesting dynamic. They're two very different men as it pertains to their criticism of the Federal Reserve, to put it bluntly. And I think that's something to keep an eye on as this goes through the rounds.

Linda Yakarino said she is stepping down as chief executive of X, capping a tumultuous run atop Elon Musk's social media company in 2023, when Yakarino took the helm of the social media platform then called Twitter. She came in with decades of experience in the advertising world. Joining me now is WSJ advertising editor Suzanne Vernica. Suzanne, what is the condition in which Linda Yaccarino is leaving X? How is its business?

[Linda Yakarino]

Well, it's funny because Linda took over this company about two years ago and it was quite a different situation. Advertisers had balked in wide numbers, leaving the platform and pausing their ad spending just because they were afraid of all the uncertainty. As Elon Musk when acquired the company and promised to redo it, open it up to more opinions and different type of content and they really were afraid that their ads were going to appear next to content that was controversial. There was also a lot of people that left X and that were fired a lot of ad salespeople. So advertisers were really nervous about who was in charge fast forward to now and Linda is stepping down. They're still not out of the woods in advertising. Spending isn't surging or anything. They're expected to finally grow ad spending this year, but they're far from close to what they made pre Elon takeover.

[Alex Osola]

Does her departure represent a pivot for the company?

[Linda Yakarino]

It comes right after the merger with Xai, and there has been speculation in the marketplace about what was going to happen with the company as these two powerful companies come together. Everybody wanted to know what would happen to Linda because she's CEO of X, and I had a hard time and so did people in the industry believing that she would want to report into anyone else except for Elon. So there's been lots of speculation about what was going to happen here. She has done a good job of bringing new things to X, like signing on more content from celebrities and shows and videos and also lots of sports content, which has made a lot of advertisers somewhat comfortable, or at least more comfortable with going back. She worked on bringing new brand safety tools, which helps advertisers keep their ads away from craziness that happens on the platform or anything controversial that they don't want to be near. It does come at this really unique time because everybody's trying to figure out what is this platform going to be. But keep in mind, like, X is where a lot of the ad revenue is. So it's still a really important piece to Elon Musk's overall mission to fund his biggest push into artificial intelligence, which we know now is really expensive and every tech company is out there spending billions, if not tens of billions of dollars to do that.

[Alex Osola]

That was Wall Street Journal advertising editor Suzanne Vernica. Major US Indexes ended the day higher as markets took President Trump's latest tariff moves in stride. The Nasdaq rose to a record high, closing up about 0.9%. The Dow climbed about half a percent, while The S&P 500 added about 0.6%, less than half a percent off its record high last week. A rally in Nvidia's shares lifted its market capitalization above $4 trillion today, a world first that caps a remarkable run for the artificial intelligence chip maker, to give you a sense of the size of that. Now, granted, market cap is a pretty different measure than gdp, but if Nvidia were a country, it would rank as the fifth largest in the world, behind only the U.S. china, Germany and Japan. That's according to the World Bank's most recent figures as of 2024. Today's milestone comes barely two years after Nvidia notched a $1 trillion closing valuation for the first time. In the end, after hitting the peak, Nvidia stock pared gains closing shy of the $4 trillion mark. Coming up, why the Justice Department is investigating one of the biggest Medicare providers. That's after the break.

[Alex Osola]

We'Re exclusively reporting that the justice department is investigating UnitedHealth Group's Medicare billing practices, including how the giant company deployed doctors and nurses to gather diagnoses that bolstered its payments. That's according to people familiar with the matter. Christopher Weaver covers U.S. health care companies for the Journal and joins me now with more. Christopher, in May, you had reported that the Justice Department's health care fraud unit was looking into UnitedHealth Group's Medicare business. What more do we know about this probe now?

[Christopher Weaver]

The investigation has continued in recent weeks. That's included a number of interviews with medical providers, including doctors and a nurse who previously worked for UnitedHealth Group. Those sources have told us that prosecutors asked them specifically about United's practices for recording diagnoses that they then submit to Medicare in exchange for higher payments. Basically, the way Medicare Advantage works is private insurers oversee Medicare benefits for seniors and disabled people, and they get paid more if people have certain medical conditions, in part to cover those extra costs. And United has, as we've shown in a series of articles that was published last year, essentially diagnosed people with those lucrative conditions at higher rates than other insurers through a number of different kind of practices.

[Alex Osola]

What does UnitedHealth say about this investigation?

[Christopher Weaver]

When we initially broke the story in May, United denied that they'd heard from the Department of Justice and said they stood by the integrity of their Medicare Advantage program. Now they've changed the tune a little bit. Now they're saying essentially that they don't want to engage with government agencies through the press and that they'll do it directly, that they've done well in audits in the past and that they've engaged a new third party process to oversee and audit their medical diagnosis recording practices. DOJ has declined to comment, as have the agencies including the FBI and the Health Department's Office of Inspector General that are also participating in the investigation.

[Alex Osola]

I'm wondering, Christopher, whether this sends a signal to other companies that they might need to change their Medicare billing practices.

[Christopher Weaver]

There's been an enormous amount of scrutiny of these practices in the last year or so, much of that driven by the Journal's reporting on the topic. United engaged in these tactics in a much more aggressive way than many other major insurers. Recently, Humana, the number two company in this space, essentially changed its public position on some of these practices, including the nurse home visit, and United eventually followed suit. The reality is that some of those other companies have a lot less to lose than United has got.

[Alex Osola]

That was WSJ reporter Christopher Weaver. Thank you, Christopher.

[Christopher Weaver]

Thank you.

[Alex Osola]

And finally, measles cases in the US have hit a 33 year high, according to data released today by the Centers for Disease Control and prevention. At least 1,288 measles cases have been reported across the US just over halfway through the year, surpassing the 1,274 cases reported in 2019. According to the CDC, more than 90% of those infected with measles so far this year were unvaccinated or had an unknown vaccine status. The climbing case count is fueled largely by an outbreak that began in West Texas and spread to other states in 2025. The vaccine preventable disease has hospitalized hundreds and resulted in the first US Measles related deaths in a decade. And that's what's news for this Wednesday afternoon. Today's show is produced by Pierre Bienname with supervising producer Michael Kosmides. I'm Alex Osolov for the Wall Street Journal. We'll be back with a new show tomorrow morning. Thanks for listening.
