Idaho Sen. Larry Craig resigned Saturday following his arrest for soliciting sex from an undercover police officer in an airport bathroom, bowing to pressure from fellow Republicans worried about a scandal dimming their election prospects in 2008.
"I apologize for what I have caused," Craig said.
Craig's resignation completed a stunning downfall that began Monday with the disclosure that he had pleaded guilty to a reduced charge following his arrest during an undercover police operation in a Minneapolis airport men's room.
