CDC nominee says she won't betray science — while declining to challenge
Kennedy's actions
[July 16, 2026]
By MIKE STOBBE
The Trump administration's latest nominee to lead the nation' top public
health agency drew frustrated reactions from some U.S. senators on
Wednesday when they pressed her on whether she would protect the Centers
for Disease Control and Prevention from political meddling.
Dr. Erica Schwartz told the Senate health committee she "will never
betray the science” and pledged to use “radical transparency” in a bid
to rebuild public trust in the agency. But several senators questioned
how she might handle pressure from Health Secretary Robert F. Kennedy
Jr., who has repeatedly moved to alter U.S. vaccine and CDC policies.
Schwartz repeatedly declined to dissent from some of those actions.
Schwartz, 54, is up for director of the Atlanta-based CDC, 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.
CDC has had several leaders
The agency is overseen by Kennedy, 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.
Schwartz said she was unaware of actions that hurt the CDC
On Wednesday, some senators suggested Schwartz should follow Monarez's
example, and they asked her about actions Kennedy has taken that have
affected CDC.
Schwartz said she was unaware that CDC programs that worked to prevent
smoking and promote vaccinations had been curtailed. She declined to
commit to taking down a CDC website that suggests there’s a link between
childhood vaccines and autism (she said she had not seen it), though she
agreed existing medical evidence has not found a link.
Sen. Maggie Hassan, a New Hampshire Democrat, asked if she would — if
Kennedy ordered her — suspend promotion of a flu vaccination campaign
during a deadly flu season.
“Senator, I don’t speak in hypotheticals,” Schwartz responded.

 “It isn’t hypothetical. It
happened,” said Hassan, referring to internal CDC emails, released
by Sen. Bernie Sanders last month, that documented such a directive
from Kennedy to CDC staff last year.
Schwartz said she agreed that CDC should prioritize responding to
infectious diseases. “I think over time, the CDC has had some
mission creep, and it’s trying to be all things to all people,” she
said.
But she also agreed to requests from Republican senators to — if
confirmed — look into whether AI data centers cause health problems
and into the possibility of establishing a World Trade Center Health
Program clinical center in Florida.
Senators also heard from nominee overseeing health emergency
preparedness
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.
At Wednesday's hearing, senators also considered 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.
On Wednesday, Kaufman faced questions about past social media posts,
including one in which he expressed hatred for the CDC. He also
repeatedly was asked about his support of a Trump administration
decision last year to cancel 22 projects, totaling $500 million, to
develop vaccines using mRNA technology.
Infectious disease experts say the mRNA technology used in vaccines
is safe, and they credit its development during the first Trump
administration with slowing the 2020 coronavirus pandemic. Future
pandemics, they warned, will be harder to stop without the help of
mRNA.
Kaufman said he supported mRNA technology and believes COVID-19
vaccines are safe and effective, but said it made sense to study
work that's been done so far before, including learning more about
any side effects.
Sen. John Hickenlooper, a Colorado Democrat, said such evaluations
are the responsibility of other federal offices — not ASPR. He also
said it may slow the nation's ability to respond to emerging new
infectious threats.
