Elon Musk, the world's richest man, is to spend election night with Donald Trump in Florida at his Mar-a-Lago resort, he said on X/Twitter, Report informs via the BBC.
Mr Musk, the owner of Tesla and X, has aggressively campaigned for the Republican candidate in swing states across the country.

The tech billionaire has emerged as one of the most important backers of Trump and donated more than $119 million this election cycle to America PAC - a political action committee he created to support the former president.
Musk announced his support for the former president earlier this year, despite saying in 2022 that "it's time for Trump to hang up his hat and sail into the sunset."
He posted a photo of himself on Tuesday saying he voted in Cameron County, Texas - where some of his companies are headquartered - before heading to Florida.
At the Palm Beach convention centre on Tuesday night, as the state of Florida was projected as a win for Trump, huge cheers erupted in the crowd.

In the crowd, there’s a sea of red Maga hats and other unique and eccentric outfits that have become a staple at Trump rallies.
