Story highlights Sen. Richard Shelby said he chose a write-in candidate over Roy Moore

Shelby said he doesn't have a reason not to believe the allegations against Moore

Washington (CNN) Sen. Richard Shelby says he wants a Republican elected to the Senate on Tuesday to represent Alabama, but that he didn't vote for GOP candidate Roy Moore in the special election.

The Alabama Republican said he's already cast his ballot, and that he chose a write-in candidate.

"I'd rather see the Republican win, but I'd rather see a Republican write-in. I couldn't vote for Roy Moore. I didn't vote for Roy Moore," Shelby told CNN's Jake Tapper on "State of the Union."

Moore has been accused of pursuing sexual relationships with teenagers when he was in his 30s. In some cases, the women who have come forward about the relationships have alleged sexual abuse or assault. Moore has denied all the allegations.

Shelby said in November that he would probably write-in a candidate instead of casting a vote for Moore.
