".. pelosi gets it, how come FatAss Hastert doesn't????"
it's the Ole Congressional You Scratch My Back Game. Hastert stands up, at least theoretically, for the special rights and privileges of the House as a whole; Nancy applauds Hastert, and her part is to ask Jefferson to give up his committee seat, which, in turn, Hastert will applaud.
Unless Jefferson resigns, it takes away from Nancy's "Culture of Corruption" hand, YET, she can say she tried to strip him of a very highly prized committee seat.
This Round Winner: Pelosi
Scrub that. There is something up here and Jefferson has the ability to talk about who the money was really being collected for. He is likely just a step and fetch bagman for someone else, which is why Pelossi wants him off the committee and into the shadows.
Stay in your seat Jefferson, and look to the party of Lincoln to save tour a$$.
