Cain backtracks on trading Gitmo prisoners

GOP presidential candidate Herman Cain said Tuesday afternoon he would authorize a swap of prisoners at Guantanamo Bay, but in Tuesday evening's debate he changed course.

Cain told CNN's Wolf Blitzer: “I could see myself authorizing that kind of transfer” when asked if he would trade a captured American serviceman for all of the prisoners in Guantanamo Bay be released.

During the debate, Cain said, "I would have a policy that we do not negotiate with terrorists. We have to lay that principle down first."
