House Republicans are aiming to slash funding for the nonpartisan watchdog for waste, fraud and abuse within the federal government by nearly half in the next fiscal year, according to spending bill text released Sunday night.

The House Appropriations subcommittee funding Congress and its support agencies, led by chairman David Valadao (R-Calif.), is set to mark up their fiscal 2026 measure Monday evening, with the full committee set to act Thursday. The Legislative Branch bill would provide $6.7 billion — $51 million below the current funding level, which was set in fiscal 2024. Per tradition, the House bill does not touch any Senate funding.

“Chairman Valadao’s bill puts the American people first — in strengthening the institutions that represent them, protecting effective governance, and safeguarding taxpayer dollars,” said House Appropriations Committee Chair Tom Cole (R-Okla.) in a statement.

The deepest cuts in the bill are to the Government Accountability Office, an arm of Congress that would see a $396.5 million reduction from current levels to $415.4 million.

GAO has served as the nation’s chief investigator of wrongdoing at federal agencies for more than a century, but has been fighting for months as Republicans in Congress and the Trump administration have attempted to undercut its legal conclusions and independence. Now, they are attempting to shrink the agency into submission as it pursues nearly 40 investigations into whether the White House is illegally withholding, or “impounding,” money Congress had previously approved.

Also tucked into the bill is a major policy change that would eliminate the GAO’s ability to bring civil action against the executive branch over impoundments of funds.

“GAO’s work makes it possible for the legislative branch to hold government accountable,” said Daniel Schuman, executive director of the American Governance Institute. “Congress needs independent expert advice, which is exactly what GAO provides.”

Also on the chopping block is the Library of Congress, which is another legislative branch agency also engaged in a power struggle against intrusion by the Trump administration. The bill allocates $767.6 million for the Library of Congress, which is $84.5 million below the current funding level and $133.7 million below the FY26 request.

“This bill does nothing to safeguard against the growing levels of executive overreach into legislative branch agencies,” said Rep. Adriano Espaillat (D-N.Y.), the top Democrat on the legislative branch subcommittee.

Some other key provisions in the GOP-written bill include:

Capitol Police: The Capitol Police would see a $84.4 million boost to their funding under the bill, bringing the total to $891 million. Some lawmakers had asked for an increase in office funding for use for security, but the bill flat-funds the Members Representational Allowance, which can be used for some member security purposes.

Member Pay: The bill would continue the member pay freeze that has been in effect since 2013, halting automatic cost of living increases that members of Congress are supposed to get under law.

Gay marriage: The bill includes language that prohibits discrimination against any person who “speaks, or acts” in accordance with a “sincerely held religious belief, or moral conviction, that marriage is, or should be recognized as, a union of one man and one woman.”
