Sen. Tom Coburn (R-Okla.) said at a town hall Wednesday that President Obama may not have committed impeachable offense yet, but that he's getting "perilously close."

"I think those are serious things, but we're in serious times," Coburn said in Muskogee, Okla., when asked about impeachment. "And I don't have the legal background to know if that rises to 'high crimes and misdemeanors,' but I think you're getting perilously close."
