Kristi Noem for Homeland Security SecretaryFormer Director of National Intelligence John Ratcliffe for CIA directorFormer Arkansas governor Mike Huckabee for Ambassador to IsraelInvestor Steve Witkoff for Special Envoy to the Middle EastBusinessman Elon Musk and former presidential candidate Vivek Ramaswamy for the Department of Government EfficiencyTrump says Musk and Ramaswamy's appointments are temporary. Both will wrap up their work by July 2026."They will dismantle government bureaucracy, slash excess regulations, cut wasteful expenditures, and restructure federal agencies," Trump said in a statement. "They will drive large scale reform, and create an entrepreneurial approach to government never seen before."Musk has also made promises to "send shockwaves through the system, and anyone involved in government waste."Traditionally, most of Trump's appointments would require Senate confirmation, but the president-elect wants Republicans to let him bypass that step and install appointees for up to two years.Trump's nominees for the special envoy to the Middle East and the Department of Government Efficiency are exempt from Senate confirmation.
