Bill Kristol reacted Thursday to the personal criticism of Ted Cruz among his congressional colleagues.

“There’s an awful lot of people in a petty way taking out their unhappiness, their dislikes, and I guess they’re entitled to. For me, and this is just my own view, Donald Trump should not be president. So if you think that in a strong way, you’re willing to put a lot of other things aside and try to do your best to stop Donald Trump from being president.”
