WASHINGTON — Senator Mitch McConnell, the majority leader, who has argued for weeks that Roy S. Moore, the Alabama Senate candidate, should leave the race, said on Sunday that he was “going to let the people of Alabama make the call.”

Asked during an appearance on ABC News’s “This Week” whether he thought Mr. Moore, who has been accused of preying on teenage girls, should be in the Senate, Mr. Connell said the decision should be left to the Dec. 12 special election.

“This election has been going on a long time,” Mr. McConnell said. “There has been a lot of discussion about it. They are going to make the decision a week from Tuesday.”

In the past, Mr. McConnell had said that he was looking at drafting a write-in candidate for the election, and that if Mr. Moore, a Republican, won the race, he would support a Senate Ethics Committee investigation into the allegations against him.
