CNN’s Jake Tapper posed a similar question to Christie, another potential 2016 candidate: “Knowing then what we know now — no WMD in Iraq, et cetera — was that the right decision to go to war?”

The New Jersey governor said he wanted to answer Tapper’s question directly.

“If we knew then what we know now and I was the President of the United States, I wouldn’t go to war,” he told Tapper. “But we don’t get to replay history.”

Christie said that he believed former President George W. Bush did make “the best decision he could at the time” given the information coming from the U.S. intelligence community and the situation on the ground in Iraq.
