Ken Buck Joins Other Tea Partiers' Hesitance About McConnell

Colorado Republican Senate candidate Ken Buck said Tuesday night he wouldn't commit to supporting Mitch McConnell (Ky.) as Senate GOP leader.

Buck joined several other Republican Senate candidates aligned with the Tea Party movement who haven't yet signed on to supporting McConnell as the party's top official in the Senate.

"You know, I'm going to make that decision when we get there," Buck said on the Fox Business Network when asked if he'd be supporting McConnell for leader. "I am not going to try to guess who's running and who's not running."
