The revolving-door leadership of the nation's top public health agency took another potential turn on Wednesday, as Dr. Erica Schwartz's nomination came before a U.S. Senate committee.
Schwartz, 54, is up for director of the Atlanta-based Centers for Disease Control and Prevention, which is charged with protecting Americans from preventable health threats.
Her career has largely been spent in military uniform, including in a leadership position at the U.S. Coast Guard where she oversaw the organization’s system of 41 clinics and 150 sick bays — as well as policies promoting vaccinations of service members. She later served as deputy surgeon general, where she helped lead uniformed medical and health professionals posted at the CDC and government health agencies that serve the general public.
The CDC long enjoyed a sterling international reputation but has been in turmoil since Trump returned to office last year. Largely due to layoffs and resignations, the agency has lost more than 3,000 employees, or more than a quarter of its workforce. Morale has plummeted as a succession of mostly temporary leaders have come and gone — the front office filled with political appointees, many of them with little or no training in medicine or public health.
“There’s still really good people who work there (at the CDC). They are doing their best to navigate choppy waters,” said Dr. David Margolius, director of Cleveland's health department and a leader in a U.S. coalition of big city health departments. But CDC no longer seems to the authoritative and communicative lead that it was on outbreaks and other public health emergencies.
“Basically everybody’s got to kind of choose their own adventure, as opposed to being led by a national public health department,” Margolius said.
The agency is overseen by Health Secretary Robert F. Kennedy Jr., who was a leading voice in the anti-vaccine movement before he was tapped to lead the CDC and other federal health agencies. Kennedy had promised not to change the nation’s vaccination schedule. But shortly after taking office, Kennedy said he was going to investigate the childhood vaccine schedule and went on to attempt a substantial rewrite of vaccine recommendations for kids. Some of those efforts were put on hold earlier this year by a federal judge.
The administration’s first pick to run the CDC was former Florida congressman Dr. David Weldon, but his March 2025 Senate confirmation hearing was canceled an hour before it was to begin. Weldon said at the time that he’d been told not enough senators were willing to vote for him.
The White House then moved on to Susan Monarez, who had been serving as the CDC’s acting director. Monarez was confirmed by the Senate, but she was ousted in less than a month. Trump administration officials said she wasn’t aligned with their agenda so they terminated her.
Several key CDC scientific leaders resigned in protest, saying Monarez’s dismissal dashed their hopes that a CDC director would be able to guard against political meddling in the agency’s scientific research and health recommendations.
Since then, there’s been a revolving door in agency leadership, with the short-term role of acting director being passed from one Washington-based HHS official to another. National Institutes of Health Director Jay Bhattacharya has been overseeing the CDC most recently.
In April, Trump nominated Schwartz, calling her “incredibly talented.” In a congressional hearing in April, Kennedy said he approved of the choice, but refused to commit to supporting whatever vaccine guidance she might issue.
Last month, Schwartz filed letters with the government that address her finances and potential conflicts of interest. She wrote that if confirmed, she will leave her current job with UnitedHealth Group, where she's making about $850,000 in salary and bonus money and cash out her stock options. She also will resign from the board of directors of Butterfly Network Inc., a Massachusetts company that makes ultrasound devices; from the board of Atlanta-based Aveanna Healthcare, a medical home care provider; and from the board of the Florida-based Searching for Solutions Institute.
Also at Wednesday's hearing, senators will consider the nomination of Sean Kaufman as the Assistant Secretary for Preparedness and Response, or ASPR. That job entails overseeing preparations and response to public health emergencies and disasters.
Last year, the Trump administration announced a plan to bring those responsibilities under CDC, but the dramatic HHS restructuring has not happened.
The assistant secretary's office is involved in decisions about funding next-generation vaccines against pandemic flu or other infectious disease threats. In postings on LinkedIn, Kaufman has made comments cheered by vaccine skeptics, arguing against hepatitis B vaccinations for newborns and saying he served as an expert witness to advocate for people who refused the COVID-19 vaccine.

WASHINGTON (AP) — President Donald Trump wants Immigration and Customs Enforcement officers to keep pulling over vehicles, signaling his opposition Wednesday to plans announced just a day earlier to suspend most traffic stops following another string of fatal shootings.
It's not clear whether ICE will quickly reverse course and resume most stops, which have been a key tool in Trump's immigration crackdown.
Ending those stops, Trump wrote, would be “playing right into the criminal’s hands.”
“We CANNOT give up one of ICE’s most important and effective Crime Fighting tools, THE TRAFFIC STOP!” Trump wrote Wednesday on his social media site.
Hours after Trump made his views known, Homeland Security Secretary Markwayne Mullin issued his own statement saying people illegally in the country would be “arrested and deported wherever they are.” But Mullin didn't directly say whether ICE officers will be allowed to carry out traffic stops.
ICE's enforcement tactics are coming under renewed criticism after three people died during encounters with federal officers within a week. In Florida, a 28-year-old man was killed Tuesday after he was hit by a tractor trailer while running from immigration and other federal officers, authorities said.
Before that, two motorists were shot and killed by ICE officers — one in Texas last week and another in Maine on Monday.
After the Maine killing, Trump administration officials told ICE officers to suspend most vehicle stops, people familiar with the decision said Tuesday.
Since the immigration crackdown began, federal officers confronting drivers have opened fire several times, saying the drivers’ vehicles had posed a danger. Policing experts have long said that shooting into moving cars presents a danger of its own and should almost always be avoided.
There have been at least 10 deaths involving encounters with immigration agents since Trump launched his deportation campaign. At least four of them involved people in vehicles, a trend so troubling that Republican U.S. Sen. Susan Collins of Maine urged Department of Homeland Security leaders “to cease all non-urgent vehicle stops.”
Two shootings in a week, she said Wednesday, “raise very serious questions” and warrant a halt in that approach for the time being.
ICE has been under pressure to beef up arrest and deportation numbers. It says people being sought are increasingly staying in their homes, and it often blames immigration advocates who advise immigrants to stay in homes unless ICE produces a warrant signed by an independent judge.
ICE officers say that means they’re forced to find other ways to make arrests.
More protests are planned for Wednesday, a day after hundreds gathered to remember Johan Sebastián Durán Guerrero, the 25-year-old Colombian national who was shot in his car Monday.
Durán Guerrero illegally entered the U.S. on Sept. 1, 2023, through the southern border, DHS said Wednesday. Advocacy groups said that when he was killed, he was authorized to work in the U.S.
Sen. Angus King, I-Maine, said the Homeland Security secretary told him on Monday that ICE officers were in Biddeford to serve an arrest warrant but that it wasn't for the person who was shot.
When ICE tried to stop a vehicle driven by someone who came from a home under surveillance, the “vehicle attempted to flee the scene and, fearing for public safety, an officer discharged his weapon,” the department said.
It its statement Wednesday, DHS said Guerrero was released into the U.S. after crossing the border.
The department didn't answer questions about the agent who shot him.
Photos showed bullet holes in Durán Guerrero’s car windshield, but the officers involved in the shooting didn’t have body cameras, leaving many questions about what happened.
Outgoing Colombian President Gustavo Petro called the shooting of Durán Guerrero a targeted killing “at the hands of the U.S. government.”
In Wednesday’s social media post, Trump told ICE to be “judicious, fair and smart, and go back and do your very important job.”
Border czar Tom Homan told reporters that the investigation needs to play out and that officers will be held accountable if they are found to have acted inappropriately or illegally.
Maine’s Democratic governor, Janet Mills, said ICE should be scrapped as a federal agency if it can’t be fixed.
Mills, who has criticized ICE before, said Wednesday that the agency needs changes “before more families are robbed of a loved one.”
