Stephen Colbert is not impressed with Minnesota Sen. Al Franken’s apology to Leeanne Tweeden after she accused Franken of sexually harassing her during a USO Tour in 2006, and taking a photo showing Franken groping her while she slept. Franken apologized, stating that the photo was meant to be funny. “O.K., ‘intended to be funny but wasn’t?’’ said Colbert on Thursday’s The Late Show.
