For most of the time since Election Day, he has also been Trump's tenant.

Musk has been using one of the cottages available for rent on Trump's property at Mar-a-Lago, the former Marjorie Merriweather Post home in Florida that Trump converted into a members-only club and hotel in the 1990s, according to two people with knowledge of the arrangement. The cottage where he has been staying, named Banyan, is several hundred feet away from the main house, according to a person who knows the property.

Staying right on the grounds has helped provide Musk with easy access to Trump.

He can drop in on Trump's dinners, such as one he had recently with Musk's rival, the Amazon founder Jeff Bezos.
