Jon Stewart erupted into a fit of laughter over a Fox & Friends clip that showed how a host unsuccessfully tried to stop President Donald Trump from ranting during a Lindsey Graham 'tribute' segment.

Stewart, during Monday's episode of the Daily Show, shared a montage of Trump's news appearances after Graham's death on Saturday night.

The South Carolina senator died aged 71, with a preliminary medical examiner report saying he suffered a tear in his aorta, known as an aortic dissection. 

The president, regarded by Fox & Friends as one of Graham's best friends, has appeared on multiple news networks simultaneously remembering and roasting the late senator.

He even went as far as branding him a 'workaholic politician' that talked too much.

'It takes a lot of balls for Donald Trump to gently roast someone for yapping too much,' Stewart said, introducing the clip. 'He's the one who toasted his friend on Meet the Press, CNN's State of the Union and Fox & Friends. 

'Trump was everywhere, remembering Lindsey Graham, even when the host appeared to not want him to.' 

As he eulogized the 71-year-old on Fox & Friends, the president began by describing his relationship with Graham. He said: 'He was a great guy and he was a friend. He would call me all the time. He would just - I'd say, "Stop calling me, Lindsey."'

Stewart, in his best Trump impersonation, said: 'I'll never forget the way that I always let him go to voicemail.'

Then, resuming his own speaking voice, the host said: 'Obviously, he's just opening the eulogy on a lighthearted note. I'm sure the poignancy follows.' 

The clip continued with Trump launching rant about election fraud and repeatedly ignoring host Lawrence Jones' attempts to bring the conversation back to Graham.

'These people suffer from a very fine disease known as Trump derangement syndrome. And yeah, he was seeing that,' Trump said.

'Mr President, did you notice any-' Jones replied, but Trump kept speaking.

'He's really come a long way terminating the filibuster,' the president continued.

Jones tried to interject again: 'But Mr. President, did you notice anything different?'

'Look at California. Millions and millions of ballots. It's impossible… They didn't know in two weeks. They let it be known an hour later–' Trump continued.

Jones, yet again, attempted to steer the conversation elsewhere, but was ignored. 

'So, Mr President,' he said, but Trump continued to talk over him.

'So Mr President, real quickly, did you notice anything different from Lindsey–'

But Trump interrupted: 'And he's gonna be in the runoff.

'These elections are very dishonest.'

Stewart, stopping the clip at that point, cracked up at the exchange.

'Oh, no. I'm sorry, Mr President. The TV station's going through a tunnel. Boop!' the Daily Show host said through his chuckles. 

Graham unexpectedly died on Saturday night. His sister, Darline Graham Nordone, has since been named as his temporary replacement in the Senate.

Nordone will serve the remaining months on Graham's current term, which expires in January, South Carolina Gov. Henry McMaster announced on Monday. She will be sworn in this afternoon. 

Graham never married or had a family of his own, but Nordone was often by his side for the political touch points of his career, speaking at events and appearing in some of his campaign ads.

After their parents died at a young age, Graham was left to raise his sister, for whom he later became legal guardian. They were very close, and she was there as he filed reelection paperwork earlier this year, along with her children and grandchildren.

A special election will be held next month to pick a new Republican nominee in the general election for Graham's seat. He had been seeking a fifth term this year.
