Billionaire Democrat donor Stephen Cloobeck has been arrested for allegedly tampering with an upcoming court trial. 

The real estate tycoon, who briefly ran to become Governor of California, has been accused of attempting to prevent or dissuade a witness from testifying. 

Police records show Cloobeck turned himself in to Los Angeles cops in West Hollywood on Tuesday morning after receiving a warrant for his arrest.

He was released on a $300,000 bond at 1.17pm.

The 64-year-old founder of timeshare company Diamond Resorts has denied the allegations. 'These charges are false and we look forward to our day in court,' he said in a statement through his lawyers. 

If convicted on the felony charge, the billionaire faces up to four years in prison. The Daily Mail has contacted police for more information.

Cloobeck was a longtime donor to Eric Swalwell until sexual assault allegations against the former Democrat Congressman were aired in mid-April. 

Hours before Swalwell dropped his bid for California Governor, Cloobeck told the New York Post he was no longer supporting him and had kicked him out of his Los Angeles mansion. 

'I am no longer supporting Eric,' Cloobeck said on April 12. 'F***ing tell everyone I'm a libertarian. F*** you, Democrat Party. I'm a libertarian now.' 

Cloobeck also hit the headlines last month after his wedding to Penthouse Pet model Adva Lavie was thrown into disarray when she was accused of robbing wealthy old men.    

Lavie, 28, was ordered to wear an ankle monitor after pleading not guilty in a Los Angeles courtroom in early April to six felonies, including grand theft, burglary and unauthorized use of identifying information. 

Cloobeck gave more than $1 million to Swalwell's campaign, and he is now among hundreds of supporters trying to claw back their donations through an attorney. 

He told the Post that Swalwell had been staying at his palatial Beverly Hills mansion, but he kicked him out as soon as he heard about the sordid allegations. 

'I have a lot of people who stay at my house,' Cloobeck said. 

'I built a gorgeous place, my dream home, I relish it, and I'm a very generous man. I'm very thoughtful and I'm very kind.' 

It came just weeks after Cloobeck called Swalwell his 'little brother' during an interview with Politico, and he previously shot down rumors about him allegedly acting inappropriately with female staffers before they became formal charges. 

Swalwell has been accused of sexually assaulting at least five women, including a former employee. 

The married Congressman was among a group of Democrats leading the race to replace Gavin Newsom as leader of the nation's most populous state - but his campaign imploded days after shocking claims began emerging on April 10.  

Swalwell denied the accusations in a social media post two days later while announcing his resignation from the gubernatorial race. 'I will fight the serious, false allegations that have been made - but that's my fight, not a campaign's,' he wrote. 

The first allegation against Swalwell was aired by a former employee of Swalwell's who spoke anonymously with the San Francisco Chronicle on April 10.

She said the Democratic Congressman sexually assaulted her in 2019, when he was her boss, and again in 2024. 

The alleged victim said she was too intoxicated to consent to sex in both cases and did not go to police at the time because she was afraid she would not be believed.

Since the Chronicle story was published, at least four more women have made claims against the politician, accusing him of rape, sexual assault, and sending unsolicited messages and photographs.

Three women have spoken on the record about their alleged experiences with Swalwell, including Lonna Drewes, Ally Sammarco, and Annika Albrecht.  

Drewes, of California, told a news conference she believes Swalwell drugged and raped her in 2018 after the opening of a restaurant. 

She alleged that Swalwell choked her during the assault. 'While he was choking me, I lost consciousness. I thought I died,' she said. 

Social media influencer Sammarco said she received unsolicited nude photographs from Swalwell on Snapchat after initially reaching out to him on X to discuss politics. 

Albrecht said Swalwell also sent her 'sexually inappropriate' messages on Snapchat.  

'For me, justice won't be until he can't ever harm a woman ever again, and he has faced the consequences for the women that he has harmed,' she told CBS News. 

Swalwell has maintained that the allegations are false. He said it would be unfair to his constituents if he remained in Congress while he is distracted from his duties.

Attorney Sara Azari released a statement on Swalwell's behalf saying he 'categorically and unequivocally denies each and every allegation of sexual misconduct and assault that has been leveled against him.'

Swalwell has been married to Brittany Watts, a sales director at the Ritz-Carlton in Half Moon Bay, since October 2016, and they share three children together.  

The Daily Mail has contacted Azari and the Swalwell campaign about donor requests for refunds.
