“I like her. And I don’t know why everyone is such a hater on her. Seems like the worst job in the entire world,” McCain tells host Julie Mason SiriusXM’s “Press Pool Profile” in an interview airing Tuesday afternoon.

“I don’t know her nor have I ever met her, but my understanding is she wasn’t as enthused about [Donald Trump] running for president, maybe like my mother was when my dad ran,” said the daughter of Sen.

“I would love to hear her do more interviews and choose another platform other than cyber bullying to speak out on,” McCain, 33, added.

“Yeah, don’t know how that’s working out,” she quipped of Trump's anti-bullying stance.

While on the campaign trail in 2016, Trump called for an end to childhood bullying, saying combating it would be one of her key initiatives as first lady. She was widely mocked for the remarks by critics who pointed to her husband’s penchant for Twitter battles.

“I do like her,” McCain said. “She’s my favorite Trump, by far.”

President Trump has been critical of John McCain, both before and after taking office. He famously insulted the former prisoner of war on the campaign trail, saying he prefers war heroes "who weren't captured."

Meghan McCain also opened up about dealing with her father’s cancer diagnosis.

The lawmaker has been undergoing treatment since announcing last July that he had been diagnosed with glioblastoma, an aggressive form of brain cancer. 

“He’s good, he’s in Arizona right now doing physical therapy as a result of his chemo and radiation, the aftereffects of it. And he’s doing really good,” McCain said.

“He watches ‘The View’ every day,” McCain continued before cracking, “He’s kind of a stage dad now.”

“He’s very tough, he’s very strong,” McCain said.

She then revealed a favorite phrase of her 81-year-old father: “He says, ’Don’t let the bastards get you down.’ But he says it in Latin.”

When an audience member repeated the phrase, “Noli illegitimi carborundum,” McCain replied, “Yes, he says that all the time!”

“It must be a military thing.”

The full interview with McCain airs Tuesday at 4 p.m. on SiriusXM’s P.O.T.U.S. channel.
