President Trump on Tuesday slammed Robert De Niro as a "very Low IQ individual" who has "received to many shots to the head", after the actor's profanity-laced tirade during Sunday's politically charged Tony Awards.
The actor was bleeped when he used the F-word.
The crowd at New York's Radio City Music Hall cheered his remarks, though he was later criticized for stooping to Trump's name-calling level.

In the catalog of nicknames Trump has bestowed upon his detractors, "Punchy" has to be his worst yet.
But in a tweet, Mr Trump described the actor as "a very Low IQ individual".
"It's no longer 'down with Trump, ' it's 'f-k Trump, ' " the 74-year-old performer - who won an Academy Award for playing a boxer in 1980's "Raging Bull" - said.
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.More news: Raptors promote assistant coach Nick Nurse to replace Casey
How no one has looped that into one of those 10-hour videos of him just saying "Fuck Trump" over and over is beyond me.
"I watched him. and truly believe he may be "punch-drunk", he said.
He famously said he wanted to punch Trump "in the face" during the 2016 US Election, called him a "f***ing fool" and the "baby-in-chief" in January 2018, and the following month said the US was now suffering from a "case of temporary insanity".
