Dave Portnoy slams George Clooney in expletive-laden rant for calling on Joe Biden to step down - and fumes at Hollywood star for 'only just finding out the President is a vegetable'

Barstool Sports founder Dave Portnoy launched into a furious tirade at George Clooney on Wednesday, after the Hollywood A-lister U-turned on Joe Biden and called for him to pull out of the presidential race.

Clooney's op-ed in the New York Times stunned the world, as he asked Biden, 81, to step down just three weeks after hosting a record-breaking $28 million fundraiser for the president on June 16.

Portnoy was quick to give his thoughts on the incredible turn of events, taking to X to give his scathing take.

'What a f***ing hero this guy is,' he says of Clooney, who claimed in his piece that the President 'was not the Joe "big f-ing deal" Biden of 2010' when they met last month.

'So what, George?' Portnoy continued. 'If he didn't do the debate and wasn't a vegetable, you were just going to keep your mouth shut?

'And by the way, if you just found out Biden is a vegetable, where have you been for two years? Everyone knows he's a vegetable.

'The guy can't get on and off a stage without getting lost, he talks about dead people like he had lunch with them yesterday. He can't f***ing ride his bike without falling down. He can't get up and down f***ing Air Force One without taking a tumble.

'No f***ing s*** he's a vegetable. He's been a vegetable for two f***ing years, the Democrats don't f***ing care.'

In the clip, Portnoy then goes on to speculate about 'dirty politics' and his belief that the Democrats are trying to 'whack' Biden. 

'You have the good-looking guy from California, Gavin Newsom, waiting,' he continues, before adding: 'F*** it, let's just have Trump run vs a head of lettuce. Honestly, the votes will probably be the same!'

In his op-ed on Wednesday, Hollywood megastar Clooney said Biden can't win the 'battle against time', and condemned Democratic party leaders for ignoring 'every warning sign' of Biden's declining physical and mental health.

He added that Democrat voters 'collectively hold our breath or turn down the volume whenever we see the president, who we respect, walk off Air Force One or walk back to a mic to answer an unscripted question.'

Clooney joins the scores of Democrats and Biden allies who have called for the president to step down in the two weeks since his meandering and mumbling showing on CNN.

Biden has insisted he is not going anywhere and that he will still beat Trump in November, but Clooney's comments are an enormous blow to his embattled campaign.
