Sen. Al Franken may have once shared a television stage with Delaware Tea Party favorite Christine O'Donnell, but now the former Saturday Night Live writer is going to stump for her opponent.

The Delaware Democratic Party announced today that Franken will host an event Thursday for Delaware Democratic Senate nominee Chris Coons, who is challenging O'Donnell, the Republican candidate in the Delaware Senate race.

The campaign stop includes a Franken meet-and-greet for campaign volunteers, according to the event flyer.

Back in the '90s, Franken appeared with O'Donnell as panelists on TV host Bill Maher's "Politically Incorrect," where the pair battled on sex, condoms and welfare reform.

Franken is not the first Minnesotan to get involved in the contentious Delaware Senate race that's attracted national attention since O'Donnell upset establishment Republican Rep. Mike Castle: Last month Gov. Tim Pawlenty said he was backing O'Donnell's Senate bid.
