Washington (CNN) Since Alabama Senate candidate Roy Moore was accused by five women of pursuing relationships with him when they were teenagers, fellow Republicans have weighed in on what he should do ahead of the state's election on December 12.

Republicans' responses can be divided into a few categories, those who said Moore should step down, no caveats; those who said Moore should step down if the allegations are true; those who are defending Moore; and those who aren't saying anything.

Since the most recent accuser came forward Monday, the number of Republicans calling for Moore to drop out of the race has grown. Here are some of their responses:

Republicans who say Moore should step aside or be removed from office if he is elected:

Sen. John McCain, Arizona:

"He should immediately step aside and allow the people of Alabama to elect a candidate they can be proud of," he said in a statement Thursday.

Mitt Romney:

"Moore is unfit for office and should step aside," he tweeted Friday.

"I think Roy Moore needs to step aside now. These allegations are disgusting and I believe them," he said on "The Lead" Friday.
