Susan Monarez fired while four officials resign amid tensions over vaccine policies and public health directives.

The director of the United States’s top public health agency has been fired after less than one month in the job, and several top agency leaders have resigned.

Susan Monarez is not “aligned with” President Donald Trump’s agenda and refused to resign, so the White House terminated her, deputy press secretary Kush Desai said on Wednesday night.

The US Department of Health and Human Services had announced her departure in a brief social media post on Wednesday afternoon.

Her lawyers responded with a statement, saying Monarez had neither resigned nor been told she was fired.
