Some of the key actions taken or threatened by DOGE are at least arguably illegal without permission from Congress, such as dismantling USAID, offering "deferred resignation" firing employees without due process, unilaterally stopping payments to agencies or individuals, and some smaller ones. Beyond that, there is the FACA lawsuit challenging the organization of DOGE itself; the administration has partially mitigated that by making Musk a special government employee, but no word on the rest of DOGE.
