Elon Musk and Vivek Ramaswamy have laid out their plans for the Department of Government Efficiency (DOGE), a currently nonexistent entity they say will “cut the federal government down to size.” Though DOGE isn’t a real department — and may in fact just be President-elect Donald Trump’s way of placating Musk by giving him the appearance of a real job — it represents a long-running right-wing attempt to gut the civil service,

Elon Musk and Vivek Ramaswamy, co-heads of the Department of Government Efficiency, have suggested they’ll make cuts in key government departments, including the Pentagon.
