White House says Trump has fired CDC Director Susan Monarez

The White House on Thursday said President Donald Trump has fired Centers for Disease Control and Prevention Director Susan Monarez after she refused to resign.

Hours later, NBC News reported the White House had tapped Jim O’Neill, deputy secretary of the Health and Human Services department, to serve as acting director of the CDC. O’Neill was sworn in as deputy secretary in June, and is a key aide to HHS Secretary Robert F. Kennedy Jr.

The temporary appointment suggests that Kennedy could have a clearer path to make changes to U.S. immunization policy, particularly after Monarez had refused some of his requests. The permanent replacement for Monarez will have to be confirmed by the Senate.

During a briefing on Thursday, White House press secretary Karoline Leavitt said Trump fired Monarez, “which he has every right to do.” She said Trump has “the authority to fire those who are not aligned with his mission,” and that he or Kennedy Jr. will announce a new CDC director “very soon.”

Earlier Thursday, Monarez’s attorney Mark Zaid said Monarez would remain in the role because she is a presidential appointee and only Trump can fire her. Zaid said White House personnel had tried to fire her, not the president.

In a statement, lawyers for Monarez said they were “not aware of anything new happening.”

“Receiving an email from an HR staffer simply saying ‘you’re fired’ is insufficient as a matter of law to constitute the termination of a federal employee, especially one appointed by the president and confirmed by the Senate,” Zaid said.

He also said she “refused to rubber-stamp unscientific, reckless directives and fire dedicated health experts” and that “she chose protecting the public over serving a political agenda.”

“For that, she has been targeted,” he said.

Monarez and Kennedy were at odds over vaccine policy, The New York Times reported Wednesday, citing an anonymous administration official.

Kennedy, a prominent vaccine skeptic, has taken several steps to change immunization policy in the U.S.

Monarez was sworn in on July 31. A longtime federal government scientist, she is the first CDC director to be confirmed by the Senate following a new law passed during the pandemic that required lawmakers to approve nominees for the role.

Trump’s move to oust her is the latest in a leadership upheaval at the CDC.

At least four other top health officials announced Wednesday that they were quitting the agency shortly after HHS said Monarez was “no longer” the director of the CDC in a post on X.

In a Fox News interview Thursday morning, Kennedy declined to comment on “personnel issues.” But he said the agency “is in trouble,…
