Slander
Josh Marshall has been following the story about Speaker of the House Dennis Hastert's claims that billionaire George Soros (who has been funding a lot of left-leaning 527 organizations, including his own--America Coming Together) has funding ties to drug cartels.

I've talked to reporters who've asked Hastert this around the convention hall. And he's been aggressively restating the 'charge.' I'm told he even shoved his finger in the chest of one of them when repeating it.

What's truly amazing about this is that Hastert--the frickin' SPEAKER OF THE HOUSE OF REPRESENTATIVES--has no evidence to back this claim up:

John Feehery, a spokesman for Hastert, said, “George Soros has an agenda. He supports the legalization of drugs, and the statement stands. [Hastert] has been fighting Soros on this for years because it is a character flaw. The Speaker thinks legalizing drugs is wrong.”
[...]

Feehery cited no evidence and would not comment on whether Hastert would ask law enforcement to investigate.
