At the Tony Awards, the actor got a standing ovation when he took the stage and immediately said: "I'm just going to say one thing: F-ck Trump!". "It's no longer 'Down with Trump, ' it's 'F-k Trump'".
"I wanna say, 'F-k Trump, '" the Oscar victor exclaimed while many audience members at New York's Radio City Music Hall stood up and applauded.
Is this Trump trying to give De Niro his own nickname, like he did with Massachusetts Senator Elizabeth Warren?
De Niro is a seven-time Academy Award nominee, and won Oscars for playing Vito Corleone in "The Godfather Part II" and Jake LaMotta in "Raging Bull".
In January, he also railed against Trump while introducing Meryl Streep at the National Board of Review Annual Awards Gala.
Trump's De Niro sentiment was expressed just one hour after he had tweeted, "Heading back home from Singapore after a truly fantastic visit". He continued, "I watched him last night and truly believe he may be 'punch-drunk'". De Niro, you'll recall, appeared to say "f*** Trump", although his words were censored from the CBS broadcast.
Yesterday De Niro apologised - not for his comments but on behalf of the U.S. president. The aging actor's most recent boxing-related feature was 2016's 'Hands of Stone, ' in which he played a trainer. In January of this year, the actor called Trump a "f**king idiot" in a profanity-laced rant.
