Trump's latest fight with McCain, which began over the weekend and almost seven months after McCain's death, has centered on the president's seemingly festering resentment that McCain gave to the FBI a dossier of unverified claims about Trump and Russia that had been compiled by a former British spy named Christopher Steele.

Former Secretary of State Hillary Clinton, the Democratic Party's 2016 presidential nominee, and the Democratic National Committee tapped Washington firm Fusion GPS, which then turned to Steele, to conduct research about President Trump’s connections to Russia and possible coordination between his campaign and the Kremlin in 2016.

Trump also ripped into McCain for his vote in 2017 against GOP legislation to repeal ObamaCare.

“He was horrible what he did with repeal and replace. What he did to the Republican Party and to the nation and to sick people who could have had great health care was not good. So I’m not a fan of John McCain, and that’s fine,” he said.

A number of Republican senators have defended McCain and criticized Trump, though many others have refrained from direct criticism of the president.

The president insisted his beef with the deceased senator was started by the media.

“I didn’t bring this up, you just brought it up,” he told Bartiromo. “When they ask me the question, I answer the question. But you people bring it up, I don’t bring it up. I’m not a fan.”
