As Elon Musk, the world's richest person, put it, his role in steering President Donald Trump's Department of Government Efficiency (DOGE) has come "to an end."
However, the president, in a social media post on Thursday night announcing that he and Musk would team up for a 1:30 p.m. ET White House news conference on Friday, teased that Musk would continue to help the Trump administration.
"This will be his last day, but not really, because he will, always, be with us, helping all the way. Elon is terrific!"
Musk's political impact on national politics and on next year's midterm elections - for better or for worse - is far from over and is likely to live on well past his official departure from the Trump administration.
