Oh, about that claim Jared Loughner was linked to a right-wing group by DHS

Remember the allegation a DHS memo linked Jared Loughner to the right-wing group "American Renaissance"? The left jumped all over it. It was complete and utter BS.

Via The Plum Line at WaPo:

For the last 24 hours, the Web has been alive with speculation that the Arizona shooter has some sort of ties to a right-wing group called American Renaissance. The primary source for this claim is a Fox News report from yesterday saying that law enforcement had made this determination based on information provided by the Department of Homeland Security.

But a DHS official tells me that the department has not established any such possibility, undercutting what appears to be the primary basis for this claim.
