For all I know, William Jefferson is innocent. I'll be the first to admit that I don't know a fuckin' thing about a fuckin' thing. I'm sure there's plenty of good reasons to keep $90,000 in cash in your freezer. And a video that appears to be him taking bribes could be a misunderstanding. But as Steve Gilliard has been saying, it's time to take yourself out for the good of the party. Staying in office doesn't help anyone, probably not even Jefferson himself. Retire, and if you're found not guilty, you'll have plenty of money to live on for the rest of your life.
On the other hand, Workers World implies that it's all a COINTELPRO-esque plot to weaken the Congressional Black Caucus. Show me even a scrap of proof and we'll talk. Until then, Jefferson should get the fuck out before he's indicted.
