ProPublica has identified nine additional Musk-affiliated staffers. A former staffer at Boring Company now has an official role at DOGE in the Executive Office of the President. A former X employee now works in the General Services Administration.
It's a tad generous to accept the Trumpist claim that these DOGE [sic] contractors actually work for any part of the USG.
As the courts should do with every fact claim by this administration, check the documents. I think we'd all be amazed at how often these claims were documented after-the-fact, if at all.
