Florida Senator Marco Rubio (R) put his foot firmly in his mouth this weekend as he failed horribly to explain whether he thought the decision to invade Iraq was a mistake.

Appearing on Fox News Sunday, Rubio was asked whether he would have authorized a war knowing what is now known.

“Not only would I not have been in favor of it, President Bush would not have been in favor of it, and he said so,” Rubio said.

But, as Huffington Post points out, Rubio did not stay consistent on that point.

On Sunday, however, Rubio rejected the rationale behind host Chris Wallace’s question about whether the senator and 2016 presidential contender had flip-flopped on the issue, since he had said in March that it was not a mistake to invade the country.
