WATCH: Chris Christie calls Ted Cruz a liar over claim Hurricane Sandy aid went to 'unrelated pork' projects

Gov. Chris Christie (R) slammed Sen.Ted Cruz (R-TX) on MSNBC Tuesday night, calling him a liar for saying two-thirds of the Hurricane Sandy relief aid had "nothing to do with Sandy."

Speaking with host Chris Hayes, the blunt-talking New Jersey governor heaped scorn on Cruz for lying in the service of portraying himself as a fiscal champion.

According to Cruz, the bulk of Sandy aid distributed to New Jersey in 2012 to recover from Sandy was "filled with unrelated pork."

Cruz has been on the defensive in the wake of Hurricane Harvey damage to Texas, defending himself against claims that he and other Texas GOP lawmakers are hypocrites for requesting federal disaster relief for their state after refusing to help New Jersey in 2012.

"What was wrong was for Ted Cruz to exploit Sandy for political gain, and that's what he was doing," Christie told MSNBC's Hayes.

"The fact of the matter is that is an absolute falsehood that two-thirds of the $50 billion didn't go to Sandy aid. It's an absolute falsehood," he continued. "Let's remember what Senator Cruz was trying to do at the time: He was trying to be the most conservative, the most fiscally conservative person in the world."
