Tech billionaire Elon Musk said Monday that he and President Donald Trump were in the process of shutting down the USAID, escalating their war on the federal bureaucracy.

His statement comes as signs increasingly point to the Trump administration folding the development aid agency into the State Department.

Elon Musk called USAID a criminal organization that should “die.” Proponents say it’s a key arm of U.S. influence that, if destroyed, “cannot be easily rebuilt.”
