This is just beating around the bush. The only reason anyone even knows about RFK Jr, much less his current job, is because of Trump.
The actual solution is that Trump must go. But America voted for this. Get RFK Jr removed, and Trump will put someone just as bad, or worse, there. And the cycle continues, until Trump and the Republican Party are finally dismantled.
But I don't see that happening for quite a few years yet. The economy hasn't crashed hard enough for that to happen.
