Like father, like daughter.

Meghan McCain appeared on Fox News' "The Kelly File" Monday night to discuss Donald Trump's refusal to apologize for his recent remarks about her father's war hero status. In her first appearance as a Fox News contributor, the 30-year-old talk radio host vigorously defended her father and blasted the real estate magnate for what she claims were "gross" and "disgusting" comments.

"It's not just an attack on my father, it's an attack on all veterans and all [prisoners of war]," McCain told the show's host, Megyn Kelly.

Trump dismissed the idea that Sen. John McCain, R-Ariz., was really a war hero because he was captured.

"I don't know what he was saying. I know it was a comment from an extremely disconnected millionaire living in New York City," she added.

McCain also expressed frustration over watching her young brother return from a tour Afghanistan only to hear "his father's heroism discussed on television by a man who deferred his time in Vietnam four times."

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

Hours after McCain blasted him on the same network, Trump joined "The O'Reilly Factor" and said that "if there was a misunderstanding, I would totally take that back."

"But, hopefully, I said it correctly and certainly, shortly thereafter, I said it correctly," he added Trump.

In an ABC News/Washington Post poll released Monday, Trump topped the GOP field of candidates at 24 percent, followed by Wisconsin Gov. Scott Walker in second place at 13 percent support and former Florida Gov. Jeb Bush in third at 12 percent.
