Alongside the former presidents, family members and US officials you would expect to see at Donald Trump’s inauguration, there have also been a host of faces familiar for less traditional reasons.

We’ve seen OpenAI CEO Sam Altman taking selfies with influencer brothers Logan and Jake Paul, and controversial Irish mixed martial arts fighter Conor McGregor chatting to British politician Nigel Farage.

Also in attendance are tech billionaires like Meta’s Mark Zuckerberg and Amazon’s Jeff Bezos, media tycoon Rupert Murdoch and FIFA president Gianni Infantino.

We will continue spotting the notable and unusual names among the crowd as the day progresses.

Trump’s close and controversial friendship with X owner Elon Musk is well known but Musk isn’t the only tech chief at Monday’s inauguration.

Mark Zuckerberg, who earlier this month announced Meta was to get rid of factcheckers and “dramatically reduce the amount of censorship” on its platforms, is also in attendance.

Another tech billionaire in attendance is Sam Altman, CEO of OpenAI, who was pictured posing for a group selfie with boxer and influencer Jake Paul, and Paul’s brother, wrestler and influencer Logan.

Logan and Jake Paul also shared a selfie of them travelling to the inauguration with controversial Irish MMA fighter Conor McGregor.

Last year, a civil court found McGregor had raped Nikita Hand in a Dublin hotel in December 2018.

The Paul brothers have also had their own controversies. In 2021, Jake Paul denied sexually assaulting TikTok star Justine Paradise, after she accused him online.

At the end of last year, Logan Paul faced fresh questions over his cryptocurrency dealings amid ongoing concerns he may have profited from misleading fans.

McGregor was also pictured alongside the head of the Reform UK political party, Nigel Farage, at a Trump rally on Sunday night.

Rupert Murdoch, chairman emeritus of News Corporation, which owns Fox News, the Wall Street Journal, the Sun and the Times, is attending with his fifth wife Elena Zhukova.

Mr Murdoch, 93, married the retired Russian biologist last year in a ceremony at his Californian vineyard.

As is customary at presidential inaugurations, a host of former US presidents are in attendance.

Much has been made in the media of Michelle Obama, who attended the first Trump inauguration in 2017, not accompanying her husband Barack to Monday’s event.

There alongside Obama, who was in power before Trump’s last term began, are former presidents including Bill Clinton and George W Bush.

Another familiar face is former British Prime Minister Boris Johnson.

When Johnson took to power in 2019, Trump described him as “a good man”, adding: “They call him Britain’s Trump.”
