Moderator Anderson Cooper had no time for schoolyard excuses during the CNN Republican Town Hall, telling Donald Trump that "I didn't start it" isn't an argument that should be used by a presidential candidate.
Cooper asked Trump about his ongoing feud with rival Ted Cruz, which started after an anti-Trump super PAC circulated a racy image of Trump's wife, Melania. Trump later retweeted an image of Melania next to Cruz's wife, Heidi, in what Cooper called an "unflattering" pose.
