It is not known what his current loss stands at after stock markets were buoyed on Tuesday after Mr Trump said a deal between the US and China “will happen”.

“The stock market crashes on 9/11, yes. The stock market crashed [during] Covid, yes.

“But this is a decision that one guy made that crashed the whole stock market. That’s why we’re calling it Orange Monday and not Black Monday,” Mr Portnoy said on Monday.

“I didn’t love seeing him on the golf course playing his course championship and being like, ‘I’m a very low handicap.’ I didn’t love that,” he said, referring to comments the president made on Air Force One over the weekend, after taking Friday off to attend a golf tournament and dinner in Florida.

“The stock market is getting crushed. I’ve lost 20 per cent of my net worth. And you’re out on the golf course.”

“In my mind, Donald Trump just cost me $20 million with whatever he did. Maybe don’t be on the golf course,” he said. “Because I’m curled up in a ball in bed, sweating.”

Last month, the Barstool founder also criticised the Trump administration over the Signal leak, calling for somebody to “go down” for mistakenly adding a journalist to a group chat discussing an imminent strike on Houthi rebels.

However, Mr Portnoy added: “Do I like it? No. Am I crying, ‘Woe is me, I wish I voted for Kamala?’ No. Do I wish this didn’t go down like this? Yes,” Mr Portnoy said.

One influencer who waded into the Maga-sphere during the last election to support Mr Trump also announced he had lost at least $10 million (£7.8 million) in the market downturn.

Video game streamer Adin Ross, 24, gave Mr Trump a personalised Tesla Cybertruck and a Rolex after he appeared on his channel for an 80-minute interview.

In recent livestream Mr Ross said he had lost “eight figures” following the tariffs, to which his friend DJ Akademiks replied: “You over here like, damn, Kamala, come back to me.”

Mr Ross added: “It’s bad, I’m not gonna lie to you. It’ll get better, but it’s bad, though.”
