New Jersey Gov. Chris Christie had a big moment at the second GOP debate last night when he jumped in to stop the Donald Trump-Carly Fiorina argument about their business careers.

Christie said that campaigning in New Hampshire has taught him that Americans are looking for answers on how the middle class is going to be helped. 

"I listened to Carly and Donald go back and forth about their resumes and how much money they've made or lost. ... And I had to say, 'Listen, this is not about you, it’s about the United States.' ... I was glad to be able to call an end to the food fight because I'm sure it was getting kind of boring and tedious for the folks on the other side of the camera," he said. 

Later in the night, Christie - a former federal prosecutor - said he'd love to stand across from Hillary Clinton in a debate and "prosecute" her over her private email server. 

Christie said many Americans feel that President Obama and Clinton are acting "lawlessly" and they want someone to step in and enforce the law. 

He vowed that sanctuary cities will end immediately if he is elected president.
