Earlier this week, the South African-born billionaire, on his social media platform, X, thanked President Trump for his time at the Department of Government Efficiency, or Doge.

Trump announced he will host a news conference in the Oval Office on Friday with Musk, writing: "This will be his last day, but not really, because he will, always, be with us, helping all the way."

Let's take a look at some of the ways Musk has left a mark.
