“Personnel that should not have been cut, were cut,” Kennedy told reporters on Thursday. “We’re reinstating them. And that was always the plan. Part of the Doge, we talked about this from the beginning, is we’re going to do 80% cuts, but 20% of those are going to have to be reinstated, because we’ll make mistakes.”

It’s still not clear which staff will be reinstated or what functions the health department will retain. The huge job cuts have affected broad swaths of the department’s work, with experts lost across areas as diverse as smoking, infertility and mine safety.

The cuts to the Food and Drug Administration (FDA) included the division devoted to crafting tobacco policy, which was paid for by the tobacco industry.
