Did Sen. John McCain (R-Ariz.) kill the GOP’s latest attempt to roll back Obamacare because he holds a grudge against President Donald Trump? That was Bill O’Reilly’s theory on Friday’s “The Glenn Beck Radio Program.”

Glenn Beck argued that McCain has always been part of the more progressive wing of the Republican Party, so his vote to keep the Affordable Care Act isn’t a surprise. McCain, who was recently diagnosed with a brain tumor, was brought back to the Senate to be the “liberal lion” of the Republican Party as part of his legacy, Glenn asserted.

“I think this is about Trump,” O’Reilly objected. “I think McCain despises Trump so much because of the POW comment during the campaign.”

Trump infamously mocked McCain during his campaign for the 2016 election, saying the senator was “not a war hero” because he was taken prisoner. McCain was a Navy pilot who spent around five and a half years in a prison camp in North Vietnam where he was repeatedly tortured.

“I like people who weren’t captured,” Trump said of McCain in July 2015.
