But in a tweet, Mr Trump described the actor as "a very Low IQ individual".
This isn't the first time De Niro has gone after Trump.
De Niro a staunch Trump opponent, repeatedly dropped the f-word to an audience at the Tony Awards Sunday night while referencing Trump. He continued, "I watched him last night and truly believe he may be 'punch-drunk'". "He repeated 'F*** Trump" a second time and received a standing ovation from the crowd at the awards show for excellence in Broadway theater, held in NY.
De Niro has also made recent TV appearances on Saturday Night Live as none other than Robert Mueller, the special counsel overseeing the Russian Federation probe the President has repeatedly decried as a "witch hunt". "Fuck Trump. It's no longer down with Trump".
"I'm going to probably have to move there", De Niro joked on the day of the result.
Tesla is laying off about 3,600 workers
To those who are departing, thank you for everything you've done for Tesla and we wish you well in your future opportunities. Moreover, he said that this round of layoffs is necessary so that "we never have to do this again".
Trump, who has just left Singapore after a historic meeting with the North Korean leader, was retaliating after De Niro spent the past few days publicly denouncing Trump.
In fairness De Niro was pretty aggressive on the Tony stage, taking time away from the biggest awards show for Broadway with his curt, but pointed attack at the president. Earlier this year, the "Godfather Part II" star called Trump a "jerkoff in chief" and "a f-king idiot". On Tuesday, De Niro apologized for "the idiotic behavior of my president" in a speech at the groundbreaking of a restaurant in Toronto, CNN reported.
"It's a disgrace. And I apologise to Justin Trudeau and the other people at the G7".
De Niro has been vocal of his disapproval of the Trump administration.
