Fox News host Sean Hannity had to warn Geraldo Rivera on Tuesday that his microphone was still live and that the public was hearing insults he was uttering during Bernie Sanders' victory speech.

After Sanders won the West Virginia Democratic primary on Tuesday night, Fox News host Sean Hannity announced that he would briefly air some of the candidate's victory speech live.

"He's so annoying," Rivera complained as the broadcast cut to Sanders. "This guy is so annoying."

"Your mic is hot!" Hannity exclaimed. "What are you saying?"

"That he's so annoying," Rivera repeated. "And people that think that his supporters go to Donald Trump are smoking dope."
