Trump late Monday night fought back, suggesting his administration may investigate Musk’s companies’ massive government contracts. On Tuesday at the White House, Trump said Musk risked losing “a lot more” than government subsidies and threatened that the Department of Government Efficiency that Musk once led may “go back and eat Elon.”

US President Donald Trump threatened to look into deporting Elon Musk and cut off the billions of dollars in subsidies that Musk's companies receive from the federal government while talking to reporters at the White House on Tuesday.

Joe Gebbia, a confidant of the technology billionaire and a Tesla director, is also a leader of the federal cost-cutting team. The fight might put him in a bind.
