U.S. House Foreign Affairs Committee Chair Brian Mast on Sunday said that he supported moving USAID under the State Department and that there needs to be "more command and control".
Asked on CBS' "Face the Nation" if congressional approval was needed or whether Trump could act unilaterally, Mast did not answer but said restructuring was needed.
The "purging of people throughout the State Department, other agencies" and freezing aid were "all very important and necessary steps to make sure that we secure America," he said.
Representatives for the State Department and USAID did not immediately respond to requests for comment.
Meanwhile, billionaire Trump ally Musk on Sunday continued to slam the State Department and USAID in his posts and reposts on X. Trump has tasked Musk with leading a federal cost-cutting panel with broad oversight powers. Officials from DOGE have made frequent visits to USAID headquarters in Washington.
On Sunday, Musk accused USAID of being "a criminal organization" without providing any evidence and added "Time for it to die".
Peter Marocco was appointed as head of the Office of Foreign Assistance at the State Department and is leading the agency's sweeping changes, according to three sources familiar with the matter. Marocco previously served in Trump's first administration in the Department of Defense. The State Department did not respond to questions about Marocco.
USAID's website has been down since Saturday afternoon, a sign that the end is near for the agency, whose funding goes to programs on everything from women's health in conflict zones to access to clean water, HIV/AIDS treatments, energy security and anti-corruption work.
Reuters reported on Friday that the National Security Council hosted discussions this week on the topic and that the White House was exploring legal authorities that Trump could use to issue an executive order to end USAID's independence.
