Meghan McCain slammed Donald Trump on "The Kelly File" tonight, calling what he said about her father "one of the grossest, most disgusting comments I’ve ever heard."

The new Fox News contributor said that's because Trump didn't just attack her father, he attacked all veterans and all POWs.

McCain said that Trump is an extremely disconnected billionaire who deferred serving in Vietnam four times.

"The worst part about this is it's taking away from real conversations we should be having about the failures of the Obama administration," McCain said. "And it makes Republicans look like we're disorganized and we're in-fighting."

"And on top of everything else, any discussion about any veteran's heroism at all has no place in the national dialogue whatsoever."
