Elon Musk, the tech billionaire and self-described “dark, gothic MAGA,” will be spending election night with Donald Trump at his Mar-a-Lago estate in Florida.

Musk has spent millions on a super PAC that has supported the former president in the final stretch of the presidential race. The Trump mega donor is also under investigation for his $1 million-a-day voter sweepstakes in certain battleground states, a move that raised legal and ethical concerns.
