The rebuke comes in response to the president's tweet slamming McCain for handing over to the FBI a dossier compiled by Christopher Steele detailing compromising material the Kremlin may have on Trump.

"Spreading the fake and totally discredited Dossier 'is unfortunately a very dark stain against John McCain.' Ken Starr, Former Independent Counsel. He had far worse 'stains' than this, including thumbs down on repeal and replace after years of campaigning to repeal and replace!" Trump tweeted.

McCain defended his decision in his book titled "The Restless Wave: Good Times, Just Causes, Great Fights, and Other Appreciations," writing that he "did what duty demanded" in passing on the documents.

"I discharged that obligation, and I would do it again. Anyone who doesn’t like it can go to hell," he wrote.

McCain added that any risk the president might be compromised by Russians "had to be investigated."

McCain also drew Trump’s ire when he voted in 2017 against a plan to repeal former President Obama’s signature Affordable Care Act, indicating his vote in a now widely viewed thumbs-down on the Senate floor. McCain's vote sank the GOP’s planned "skinny repeal" legislation.
