St. Petersburg, FL (LifeNews.com) -- It came as no shock to pro-life advocates familiar with his position, but former New York City mayor Rudy Giuliani confirmed during Wednesday night's Republican presidential debate that he would not sign a bill banning abortions. The refusal was the latest confirmation that he is the only pro-abortion candidate on the GOP side.

CNN debate host Anderson Cooper asked the former mayor, "If Roe v. Wade was overturned and Congress passed a federal ban on all abortions and it came to your desk, would you sign it, yes or no?"

"I probably would not sign it. I would leave it to the states to make that decision," Giuliani said.

"I think that that -- the problem with Roe against Wade is that it took the decision away from the states. If Roe against Wade were overturned because it was poorly decided, if the justices decide that, it would then go back to the states, and it would seem to me that that would be the answer," Giuliani said.

The presidential hopeful added that the only ban on abortions he favors is one that prohibits late-term abortions or partial-birth abortions -- an issue on which he's changed his position from his days as mayor.

"I don't believe, in the circumstance that you asked before, that it should be criminalized. I think that would be a mistake unless we're talking about partial birth abortion or late-term abortion," Giuliani said.

During the debate Giuliani also restated his record and claimed that abortions went down and adoptions increased in New York City during his time as mayor.

However, LifeNews.com has previously covered how independent sources confirm that Giuliani is overstating the figures and was not directly responsible for them.
