McCain has largely refused to talk about Trump for months, despite a constant stream of questions from Capitol Hill reporters.

A reporter on Tuesday again began to ask McCain about Trump, but McCain interrupted him, reiterating he wouldn't talk about the incoming president.

"I'm not talking about Trump. I'm not talking about Trump. I am not taking about Trump," he said. "I don't know how many times i have to tell you."

McCain dropped his support for Trump's presidential campaign after a 2005 tape surfaced of the nominee discussing groping and kissing women without their consent.

Shortly after the tape was published in October, McCain told a Politico reporter to get off the Senate subway train if he intended to ask a question about Trump.

He also told reporters last week that they were wasting their time asking him about Trump.
