Walensky is lobbying Congress to make changes to the PREVENT Pandemics Act, a bipartisan bill that could be passed in the lame-duck session this month.

One of her problems with the bill, according to Roll Call, is a provision that would make CDC director a government job that requires the consent of the U.S. Senate. If passed, it would first impact her successor.

“One could imagine, especially with the politicization of CDC at the time, that that could have taken a really long time,” Walensky told the news outlet.

But Burr, the ranking member of the Senate Health, Education, Labor and Pensions Committee, does not care what Walensky thinks.

“Tough s**t,” Burr said in response to Walensky’s concern. “We desperately need to reform CDC. … This is minor compared to what we should do.”
