Robert De Niro told Donald Trump to "shut the f--- up."
The comment came on the president's 80th birthday.
De Niro wants to "love my country again."
On Donald Trump's 80th birthday on Sunday, Robert De Niro's present was a quote from one his iconic '80s movies.
While the president spent Sunday celebrating with UFC fighters at the White House, De Niro was speaking at the special Jane Fonda-hosted event Rise Up, Sing Out: A Concert for the First Amendment. And the Goodfellas star had a simple but effective message for Trump.
