Republican presidential hopefuls Herman Cain and Michele Bachmann both say they would reinstate waterboarding during interrogations of suspected terrorists, while rivals Ron Paul and Jon Huntsman both say they see the procedure as torture.
The GOP contenders split Saturday night over whether waterboarding would be an effective tool.
Cain says he doesn't support torture, but he says he would trust military leaders to determine what that means. He says he would return to waterboarding because he doesn't see it as torture.
Bachmann says she supports it, while Paul says it is illegal.
Huntsman says waterboarding diminishes U.S. standing in the world and undercuts the nation's values.
GOP contender Mitt Romney wasn't directly asked about the issue but adds he would use whatever means necessary to protect America.
