Brian Williams Uses 'Jerry Maguire' Clip to Troll Trump & McCarthy

Brian Williams put his dry-wit on full display to troll House Minority Leader Kevin McCarthy's meeting with Donald Trump -- and viewers never saw it coming.

The longtime anchor teed up the gag by earnestly telling his guests -- Baratunde Thurston and Bill Kristol -- that he'd obtained exclusive video of the highly criticized Thursday meeting between Rep. McCarthy and Trump at Mar-a-Lago.

What he ended up rolling, though ... was an iconic clip from the Oscar-nominated film, "Jerry Maguire."

The clip alone would've been funny, given the context, but Williams -- who clearly has late-night talk aspirations -- continued to sell the joke with his deadpan style ... claiming he thought it was going to be a vid of the meeting, and "someone’s gonna be, of course, in big trouble."

Trouble is a good word to describe how many anti-Trump folks feel about the Mar-a-Lago meeting between the former President and the House Minority Leader.

McCarthy's taking heat because 2 weeks ago he criticized Trump for inciting the Capitol riots, but now appears eager to work with him -- a sign Trump still has major power with the GOP.
