Don Cheadle made an explosive claim about President Donald Trump on Twitter over the weekend.

The Oscar-nominated star of 'House of Lies' was reacting to President Trump's unsupported claim that Barack Obama had been tapping his phones prior to the election when he told his followers why he disliked the commander-in-chief.

'Hated him since he asked my friend's father at a Doral pro-am if he'd ever 'f***ed a n*****...' Did it for me ...,' wrote Cheadle.

When one of his followers asked why he was just sharing this story now, Cheadle responded by tweeting: 'Many already know this to be in his nature. It's not hidden. And those who can't see it, might never. The story would have changed little.'

Cheadle would not reveal the identity of the man, but did say that he had a famous daughter.

Trump purchased the Doral courses in 2012.

Shocking allegation: Don Cheadle (left in February) claimed on Twitter over the weekend that President Donald Trump (right on Sunday) asked his friend's father if he ever 'f***ed a n*****'

'Hated him': Cheadle claimed the exchange occurred just moments after the two met during a golf tournament at President Trump's Doral golf course in Florida

The 52-year-old actor, who has been critical of President Trump many times in the past, later went into more detail about the story.

'He wasn't the president then. Just a racist, misogynistic, draft dodging, 'birther' conspiracist, p**** grabbing, bankruptcy machine...,' claimed Cheadle of when President Trump had asked his friend's father the question.

He went on to state: 'They were in a 4ball together. The Donald thought they were all "like minded." Mistook their shock for disgust.'

Cheadle then claimed: 'He went on to clarify, "No, no, it's great!" and some more stuff before they just teed off in silence.'

Many of Cheadle's followers seemed to share the actor's opinion of Trump, and one asked if the man would be willing to go on record and share his story.

'I don't know him. But his daughter is famous and probably doesn't want that particular beef for her or her dad,' said Cheadle.

When one individual dismissed Cheadle's claim and demanded proof, the actor tweeted: 'Her father wasn't wearing a wire. But look up the 2M or so articles about Drumpf and racism if you need a primer. Start with his own book.'

Cheadle also took on one man demanding proof by saying: 'If I taped her father swearing to it on a stack of bibles you'd STILL say it was a lie and you know it. There's no compelling 'proof' for U.'

He continued to tweet about the incident and answer questions all weekend, later claiming he did not know the full story during the election and that the other two people in the foursome clearly heard President Trump's comment.

'Wish you came forward during nomination to help derail this disaster,' one follower wrote to Cheadle late Sunday night.

Cheadle responded by saying: 'Again; I didn't know about it then. But I don't really think it would have changed much. You've heard the things he's said before, right?'

Timing: Cheadle said he did not hear the story until after the election when asked why he did not share it earlier

President Trump had not responded to Cheadle's allegations, and the days of Doral hosting a pro-am tournament seem to be over, with the PGA announcing last year that the annual tournament at the club would be moving to Mexico City.

That tournament was played this past weekend.

When President Trump was asked about the switch in venue last June, he ranted: 'I hope the PGA tour have got good kidnap insurance.

'The PGA Tour has put profit ahead of thousands of American jobs, millions of dollars in revenue for local communities and charities and the enjoyment of hundreds of thousands of fans who make the tournament an annual tradition.'

There were no reports of anyone being kidnapped at the tournament which was won by Dustin Johnson.
