The largest US government workers’ union and an association of foreign service workers sued the Trump administration.

The lawsuit, filed in Washington, DC federal court by the American Federation of Government Employees and the American Foreign Service Association, seeks an order blocking what it says are “unconstitutional and illegal actions” that have created a “global humanitarian crisis”.

President Donald Trump, Secretary of State Marco Rubio and Treasury Secretary Scott Bessent are among the named defendants, but the text of the suit focuses extensively on actions, and statements on social media, by Elon Musk and his “department of government efficiency” initiative.

“USAid provides life-saving food, medicine, and support to hundreds of thousands of people across the world. Without agency partners to implement this mission, US-led medical clinics, soup kitchens, refugee assistance programs, and countless other programs shuddered to an immediate halt.”
