Senate Majority Leader Mitch McConnell said Tuesday that the Senate would immediately begin the process of trying to expel Judge Roy Moore if he were to win the Alabama Senate race, after five women have come forward and charged Moore with sexual assault and otherwise trying to date teenage girls while he was in his 30s.

McConnell, R-Ky., said that if Moore wins, he would be seated and sworn in as a senator. But continuing to serve in the chamber would be an entirely different situation.

"Continued service, however, is a different matter," McConnell told the Wall Street Journal's CEO Council on Tuesday. "I think it's safe to say that if he were to be sworn in, he would immediately be in a process before the Senate Ethics Committee under which women would be sworn in. He would be sworn in. He would be asked to testify under oath as well."

"It would be a rather unusual beginning," McConnell said with a laugh. "Probably an unprecedented beginning."

"As you can see, this is a heck of a dilemma for us," McConnell said.

National Republican Senatorial Committee Chairman Cory Gardner, R-Colo., has already said the Senate should expel Moore if he wins.

McConnell said that he spoke to President Trump on Friday about the issue, as well as Vice President Pence and John Kelly, White House chief of staff, in recent days about the issue as they weigh their options. Republicans are at risk of either losing what had been a relatively safe Senate seat to Democrats, or the embarrassment of having to seat Moore.

At the same event, McConnell floated Attorney General Jeff Sessions, who previously held the seat before leaving to run the Justice Department, as someone who could launch a successful write-in campaign.
