New Jersey Gov. Chris Christie (R) said Thursday that GOP presidential rival Donald Trump has the right mindset to be president.
“Donald’s a great guy and a good person. But I just don’t think that he’s suited to be president of the United States,” he told Fox News host Greta Van Susteren as they walked along the Jersey Shore.
He added: “I don’t think his temperament is suited for that and I don’t think his experience is.”
Christie, often accused of having his own temperament issues, was responding to Van Susteren asking if he would be willing to “take a swipe” at at the Republican front-runner and real-estate tycoon.
