Republican Sen. Richard Shelby (Ala.) on Sunday said that he could not vote for Alabama’s Senate candidate Roy Moore on Tuesday and that he has already cast a write-in vote for another Alabama Republican.

CNN’s “State of the Union” host Jake Tapper said Shelby had already acknowledged he didn’t vote for Moore during early voting and then asked him who he would like to see win in the special election on Tuesday.

“Well, I would rather see the Republican win, but I hope that Republican would be a write-in,” Shelby said. “I couldn’t vote for Roy Moore. I didn’t vote for Roy Moore, but I wrote in a distinguished Republican name and I think a lot of people could do that. Will they do it? I’m not sure.”

He went on to say as a Republican, he wanted to vote for Republican, but could not vote for Moore based off the accusations against him.

The Washington Post reported last month that Moore, 70, initiated a sexual encounter with a 14-year-old girl when he was 32 years old. Three other women in the article accused him of pursuing relationships with them when they were between the ages of 16 and 18 and he was in his 30s.Moore has denied these and other allegations of sexual misconduct that have come forward over the past month.

“When it got to the 14-year-old story that was enough for me. I said I can’t vote for Roy Moore,” Shelby said.

Tapper said that Moore or his Democratic opponent Doug Jones will be Shelby’s fellow Senator after Tuesday’s special election. He then asked him which of the two candidates he would like to deal with the most on a professional level.

“Well, I don’t have to answer that question today … I’m not going to vote for the Democrat. I didn’t vote for the Democrat… I couldn’t vote for Roy Moore. The State of Alabama deserves better,” he said.

Shelby was later asked by Tapper whether he would disclose which Republican he cast his write-in ballot for, but he declined to say.

The Senate special election will be held Tuesday.
