cassidy is a maga asshole. He was the tie breaker who confirmed wormbrain. Why did she go to him? So what did he do, he went straight to the guy she was complaining about and fucked her over.
The second reason that Monarez was fired was because she reached out to a U.S. Senator.
Monarez is a Senate-confirmed appointee. She has every right to talk to members of Congress who care about the mission of her agency. After all, Congress establishes that mission in statute and via appropriations. If you want a government where RFK Jr. is the only official allowed to talk to Congress about public health, then you have settled for a government where Congress can’t fulfill it’s oversight function.
After the Monday meeting, Monarez spoke with Senator Cassidy about the threats to a policy he cares intensely about: access to vaccines. Cassidy, in turn, called RFK Jr. to share his concerns. RFK Jr. was furious with Monarez, labeling her a leaker. He simply does not want Congress to know or interfere with his anti-vax crusade to the greatest degree possible.
