US President Donald Trump has lashed out at Hollywood actor Robert De Niro after the star denounced him with an expletive-laden speech at an awards ceremony.

De Niro, who has previously said he would like to punch the president, received a standing ovation for his two-word attack at the Tony Awards.

But in a tweet, Mr Trump described the actor as “a very Low IQ individual”.

“I watched him… and truly believe he may be ‘punch-drunk’,” he said.

His expletives were bleeped by the CBS network for millions of television viewers but still garnered a huge amount of reaction on social media.
