WASHINGTON (CNN) - Former North Carolina Sen. John Edwards got applause from the audience after saying he regretted voting for the Iraq war.

"I think I had the information I needed," Edwards said. "I don't think that was the question. I think one difference we do have is I think I was wrong. I should never have voted for this war."

Edwards' answer was in response to a question that he had not read a key intelligence report about Iraq leading up to his vote. Sen. Hillary Clinton, who had also voted to authorize the war, said she based her decision on the information available at the time and did not apologize for her vote.
