Rubio had painted Christie as agreeing with President Barack Obama too closely on issues such as gun control and Common Core curriculum standards. Christie responded to those comments in a conversation with the newspaper.
“I just don’t think Marco Rubio’s going to be able to slime his way to the White House,” Christie was quoted as saying. “He wants to put out a whole bunch of negative ads? Go ahead. I hope that he will acknowledge at some point that I couldn’t care less.”
Ohio Gov. John Kasich had also criticized Christie in New Hampshire where the GOP hopeful placed pamphlets in mailboxes that said Christie had a "tough talk, weak record," according to the Post.
