Actor Robert De Niro has released a video lambasting the Republican presidential candidate.
"I means he's so blatantly stupid," De Niro says, sitting in front of the camera.
"He's a punk, he's a dog, he's a pig, he's a con, he's a bulls*** artist, a mutt who doesn't know what he's talking about."
De Niro went on to describe Trump as an embarrassment to the country, saying he doesn't do his homework and doesn't pay his taxes.
He said he cared about "the direction of this country" and was worried that it might go in the wrong direction if Trump were elected.
The video emerges as a barrage of Republicans and other politicians withdraw their support or call for Republican presidential candidate Donald Trump to quit the presidential race.
Senator John McCain said on Saturday that he would withdraw his support from Donald Trump and will instead write in the name of 'some good conservative Republican who is qualified to be president.'
Donald Trump's lewd videotaped remarks about women threw his White House campaign, and the Republican Party as a whole, in crisis just 30 days from the election Saturday, on the eve of his second debate with rival Hillary Clinton.
Trump nevertheless rejected growing calls from elected members of his own party that he step aside in the presidential race over the 2005 remarks, insisting there is "zero chance I'll quit."
Trump's own wife Melania said she was offended by her husband's comments, which were caught on a hot mic just months after the two married, the real estate magnate's third marriage, boasting about his ability to grope women as he pleases.
But she urged American voters to accept his apology and support him.
"The words my husband used are unacceptable and offensive to me. This does not represent the man that I know," Melania Trump said in a statement.
"He has the heart and mind of a leader. I hope people will accept his apology, as I have, and focus on the important issues facing our nation and the world."
