New York: Oscar-winning actor Robert de Niro issued an expletive-laden denunciation of US. President Donald Trump during the live television broadcast of the Tony Awards ceremony on Sunday.

De Niro appeared on stage at New York’s Radio City Music Hall to introduce rocker and Tony Awards performer Bruce Springsteen.

‘I’m gonna say one thing. Fuck Trump,’ De Niro said, without any preamble.

With the audience of theatre actors, directors and producers shrieking and rising to their feet in applause, De Niro said: ‘It’s no longer down with Trump. It’s fuck Trump.’

He did not elaborate on his comment and switched immediately to a prepared introduction of Springsteen.

‘Bruce, you can rock the house like nobody else,’ De Niro said. ‘And even more important in these perilous times, you rock the vote, always fighting for, in your own words, Truth, transparency, and integrity in government. Boy, do we need that now.’

The expletive, known as the F-bomb, was bleeped by the CBS network for millions of television watchers at home.

However, it was heard by those in the audience and journalists covering the awards show, which honors the best of Broadway theatre, and it quickly became the top trending item on Twitter.

De Niro is one of the most respected actors in the United States with two Oscar wins for ‘Raging Bull’ and ‘The Godfather: Part II.’

‘Mr. De Niro’s comments were unscripted and unexpected,’ CBS said in a statement. ‘The offensive language was deleted from the broadcast.’

The White House did not immediately return a request for comment.

De Niro, a noted liberal, has been increasingly critical of Trump, a Republican, at smaller showbusiness events, but none have the high profile and audience of the Tony Awards.

The Tony Awards show was seen by some six million Americans last year.
