Since taking office for his second term, President Donald Trump has issued a number of orders which included establishing the Department of Government Efficiency, also known as DOGE. This program, led by Musk, has caused a stir by going through government programs to validate funding.

A New York federal judge issued an order blocking DOGE's access to treasury payments after 19 Democratic state attorneys general sued the Trump administration.

Internal email lists and other documents and interviews provide the widest view so far of who is working in DOGE — and officials inside other agencies with Musk connections.
