Chris Christie: “If you can't say the former president is unfit, you're unfit yourself.”

This is against type for him. I'm sure it was a difficult decision. I think his analysis was, he cannot live with a nuclear weapon in Iran, and Israel did all of the heavy lifting.

“Once you go through the thought process of convincing yourself that you can be president, and then the next step that you should be president, that doesn’t leave your brain.”

“I’m going to make sure that in no way do I enable Donald Trump to ever be president of the United States again.”

This is not a message of unity in the face of what could have been a national tragedy.
