Billionaire Elon Musk, Tim Cook, Jensen Huang, and soccer superstar Cristiano Ronaldo were among several high-profile attendees at President Donald Trump’s black-tie dinner for Saudi Arabia’s de facto leader, Crown Prince Mohammed bin Salman, on Tuesday night.

The black-tie dinner was the first time Musk had been at the White House since he left his role as a “special government employee” heading the Department of Government Efficiency (DOGE) in May, then publicly feuded with Trump.

The billionaire’s attendance is the latest sign of thawing tension between him and Trump as Musk’s threat to start his breakaway “America Party” appears stalled.
