Top Democrats on Capitol Hill are leveraging all the tools at their disposal as they rail against Elon Musk’s efforts to gut federal agencies and recent access to the federal government’s payment system.

Donald Trump bungled Elon Musk’s name once again on Monday. The president accidentally referred to the tech billionaire as “Leon.” Fox News aired the gaffe. It came as Trump signed an executive order to create a sovereign wealth fund and as he fielded a question on why Musk (who is leading the non-official Department of Government Efficiency’s drive to cut public spending) should have access to Treasury Department payment systems.

Elon Musk said President Donald Trump agreed the US Agency for International Development needs to be “shut down,” following days of speculation over the future of the agency after its funding was frozen and dozens of its employees were put on leave.
