Al Franken is due to make a statement later today amid growing calls for him to step down following broadcaster Leeann Tweeden's accusations that Franken left her feeling "disgusted and violated" when they were both part of a 2006 performance for troops.

Actor Tom Arnold has taken to Twitter to criticize Tweeden.
