Arizona Sen. John McCain, who has campaigned for Indiana Senate candidate Richard Mourdock, told CNN's Anderson Cooper Wednesday that his continued support "depends on what he does."

"If he apologizes and says he misspoke and he was wrong and he asks the people to forgive him," McCain said. "It's when you don't own up to it that people will not believe in you."

Mourdock said during a debate Tuesday night that life is a "gift from God" and that "even when life beginns in that horrible situation of rape, that is something that God intended to happen."

Republican presidential nominee Mitt Romney has said that he disagrees with Mourdock's comments, but will continue to support him.
