Craig resigns

From NBC's Domenico Montanaro
Sen. Larry Craig (R-ID) has resigned. After two days of speculation that Craig would step down, the senator, who pleaded guilty to disorderly conduct after a sex-sting incident in a Minneapolis airport men's room, he said he will leave his post on Sept. 30.

"I apologize for what I have caused," said a somber Craig with his wife, daughter and Idaho Gov. Butch Otter beside him. "I'm deeply sorry."

He added, "I have little control over what people choose to believe," but to continue to serve would be an "unwanted distraction."

Craig said it was "humbling" to have his family, Otter and other Idaho politicians with him.

"For any public official at this moment in time to be standing with Larry Craig is in itself a humbling experience," Craig said.

To applause, Craig said, "It is with sadness and deep regret that I intend to resign from the senate effective Sept. 30th."

Idaho Lt. Gov. Jim Risch is widely thought to be a strong possibility to replace Craig.

Craig's resignation comes as a growing chorus of Republicans publicly chastised Craig and called for his resignation.
