Maine Republican Senator Susan Collins says she’s concerned about Elon Musk unilaterally gutting a foreign aid agency and seizing control over the Treasury Department’s payment system.

The U.S. Agency for International Development (USAID) is primarily responsible for administering civilian foreign aid and development assistance. It has a budget of more than $50 billion. Musk has called USAID a “criminal organization.”

Collins thinks President Trump has given Musk, who was not elected and is not a government employee, far too much power. “There’s no doubt that the president appears to have empowered Elon Musk far beyond what I think is appropriate,” Collins told reporters on Capitol Hill Wednesday afternoon. “I think a lot of it is going to end up in court.”

In addition, Collins thinks the President is infringing on the constitutionally stated power of Congress to appropriate government spending. “I am concerned if the Trump administration is clawing back money that has been specifically appropriated for a particular purpose,” Collins said.

Collins is the chair of the powerful Senate Appropriations Committee and has oversight over the spending that Musk is now signaling he will control.

She told the Portland Press Herald she planned to meet with a bipartisan group of lawmakers late Wednesday to discuss the actions of Musk

Collins is also critical of President Trump’s freeze of all federal grants last week, which followed a memo from the Office of Management and Budget (OMB). The memo was later rescinded after a backlash and a brief shutdown of Medicaid portals across the country. Collins said the move was “far too sweeping”.

Still, Collins says she will vote to confirm Russ Vought to lead the OMB. Vought is the author of Project 2025, a document from the conservative Heritage Foundation meant to reshape the federal government and remove checks on executive power in favor of the President’s priorities.

Vought led the OMB at the end of Trump’s last administration.
