Then if Marks spent so much of his career causing problems, why didn't RFK Jr fire him immediately? That's what most people would do, I think. RFK was sitting around waiting for his confirmation for a while. Yet he doesn't seem to have considered taking a look at the people who'd be working in "his" department?
Make some decisions, talk to the people in question.. Maybe Mark would have appreciated the courtesy, and would have sent in a normal resignation letter.
Though naturally that doesn't change the fact that RFK doesn't know what he's doing. Now kids with measles they wouldn't have contracted had be been vaccinated are being hospitalized with liver damage caused by Vitamin A.
