Trump: Never was, never will be fan of Sen. John McCain

President Donald Trump has more to say against Arizona's late senator: 'I was never a fan of John McCain, and I never will be'

"I was never a fan of John McCain, and I never will be," Trump told reporters in the Oval Office.

"He campaigned on repealing and replacing Obamacare for years and then it got to a vote and he said thumbs down," Trump said, adding — without citing evidence — that the repeal would have "saved a trillion dollars."

Over the weekend, Trump attacked McCain on Twitter. Among his barbs was that the longtime Arizona senator had been "last in his class" at the U.S. Naval Academy. But while McCain famously racked up demerits and earned poor grades, he ultimately graduated fifth from the bottom of his 1958 class.

Those attacks drew retaliatory fire from McCain's daughter, Meghan McCain.

"He spends his weekend obsessing over great men because he knows it and I know it and all of you know it — he will never be a great man," said Meghan McCain, on ABC's "The View," which she co-hosts.

Trump targeted McCain during his presidential campaign, saying in 2015 that the former prisoner-of-war was not a hero, "because he was captured." Trump received a series of deferments to avoid serving in Vietnam, including one attained with a physician's letter stating that he suffered from bone spurs in his feet.
