Senate Majority Leader Mitch McConnell called on Alabama GOP Senate candidate Roy Moore to drop out of the race after allegations by several women that he molested them or tried to date them when they were teenagers.

"I think he should step aside," McConnell, R-Ky., said at a tax event Monday that was attended by several reporters in Kentucky.

McConnell also told WLKY in Louisville on that he believes the women who are accusing Moore.

"I believe the women," McConnell said.

McConnell said a write-in campaign "is an option we are looking at," but did not commit to the idea of having Republican incumbent Luther Strange be the write-in candidate.

"We'll see," McConnell said.

In response, Moore tweeted that McConnell should be the one to step aside.

"The person who should step aside is @SenateMajLdr Mitch McConnell. He has failed conservatives and must be replaced," Moore tweeted, adding the hashtag "#DrainTheSwamp"

McConnell called on Moore to get out of the race as another woman prepared to announce accusations against Moore at an afternoon press conference. Last week, McConnell said Moore should quit the race if the allegations are true.

Polls show a tight race between Moore and his Democratic opponent, Doug Jones. Jones leads Moore in some polls while Moore is ahead in other surveys, but Moore's lead was significant in the weeks before the women came forward with their allegations.

The election is scheduled for Dec. 12.
