Robert De Niro Trump Protester Strikes Back During Broadway Show

Robert De Niro's protest chickens came home to roost -- one week after his "F**k Trump" speech, a Trump supporter gave it right back to him.

De Niro is directing "A Bronx Tale" on Broadway and, during the show's curtain call Saturday night ... a guy whipped out a Trump 2020 "Keep America Great" banner and stood by the stage. The crowd seemed to ignore him, according to some reports, and then security came and tossed him out of the theater.

The times we live in. At the end of A Bronx Tale, a man turned around and faced the audience to show us how big of a pair he has. He was escorted shortly after. It's sad that people can't enjoy a beautiful show and embrace its unifying message without politicizing it. #broadway pic.twitter.com/6tVN4Qf4d6

Mind you, De Niro wasn't on the stage when the protest went down, so it's hardly a direct hit ... as far as rebuttals go, anyway.

You'll recall, De Niro threw down the gauntlet ... cussing out the President during last week's Tony Awards.
