Aaron Blake: “One of the biggest legal questions looming over the Trump administration right now is whether Elon Musk is illegally wielding power over the American government.”“This weekend suggested he is wielding significantly more power than the White House has let on in court. Either that, or President Donald Trump’s own political appointees are defying Trump’s wishes.”“It’s all rather complicated, but the events of this weekend crystallize the chaotic and legally dubious nature of Musk’s sudden elevation to a hugely influential player in American politics and government.”
