Why it Matters
The Senate Subcommittee on Legislative Branch is set to examine two budget requests on May 12 that together could reshape how Congress maintains its physical home and manages the world's largest library. The Architect of the Capitol is seeking nearly $1.7 billion for FY2027, a 105 percent increase over enacted FY2026 funding. The Library of Congress is requesting $931.5 million, a 3.8 percent increase. Those two numbers, arriving in the same budget cycle, present the subcommittee with starkly different questions: one about whether a doubling of spending on Capitol facilities is justified, the other about whether a modest increase is enough to sustain an institution that has been buffeted by political turbulence.
The Architect's Case for Doubling Its Budget
The Architect of the Capitol's FY2027 request of nearly $1.7 billion dwarfs its prior-year appropriation. At a House Appropriations hearing in March, Rep. David Valadao noted the figure represented a 105 percent jump, a scale of increase that is rare in annual appropriations cycles and one that will demand detailed justification before senators.
The Architect of the Capitol, Thomas E. Austin, testified at that House hearing and will face similar scrutiny from the Senate subcommittee. The office oversees the maintenance, operation, and preservation of the Capitol complex, including the Capitol building itself, the congressional office buildings, the Capitol Grounds, and the Capitol Power Plant. Capital maintenance backlogs for aging federal buildings are a known pressure across the government, and the subcommittee will likely press Austin on how the agency arrived at a request that more than doubles its prior-year funding.
Adding to the oversight picture, the Architect of the Capitol's Office of Inspector General published investigation reports in early 2026, including findings related to overtime abuse and alcohol consumption while on duty. Those reports, while preceding the hearing, may surface as members question management practices alongside the budget request.
A Library Under Pressure
The Library of Congress is asking for $931.5 million, with the request intended to support staff across the institution, including the Congressional Research Service. As Rep. Valadao noted at the House-side companion hearing, the request reflects a 3.8 percent increase over enacted FY2026 levels.
The Library's budget hearing arrives against a complicated institutional backdrop. President Trump fired Dr. Carla Hayden from the Library of Congress, and the Trump administration's Department of Government Efficiency cut funding from the Institute of Museum and Library Services, a federal agency that provides grants to public libraries. Library Journal reported on the broader disruption to federal library and cultural institution funding, and CBS News documented the impact of those DOGE cuts on library systems. That political environment gives the Senate hearing added weight: senators will be examining a budget request for an institution whose leadership and federal support structure have both been unsettled in the past year.
Lobbying
Advocacy activity in the run-up to the hearing reflects organized interests on both the Library and Capitol sides of the ledger.
On the Library of Congress, one organization lobbied specifically for continuation of the Library's mass deacidification program in the FY2027 Legislative Branch Appropriations Act, a preservation effort that treats paper collections to slow deterioration. The same organization filed similar disclosures for the FY2026 cycle, suggesting sustained advocacy for a program that may not be prominently featured in the top-line budget debate but matters to archivists and preservation professionals.
More broadly, library associations lobbied on comprehensive appropriations for the Library of Congress and the Government Publishing Office, the Federal Depository Library Program, public access to federally funded research, and civil rights protections for library workers. Those filings, spanning 2025 and into 2026, reflect the library community's effort to protect institutional funding in a budget environment shaped by executive branch pressure.
On the Capitol security and facilities side, multiple organizations filed disclosures on Capitol Security and Legislative Branch appropriations across consecutive quarters, a pattern that indicates ongoing interest in how Congress funds the physical security and maintenance of its own complex.
The Subcommittee and the Hearing
Sen Deb Fischer chairs the subcommittee, with Sen. Martin Heinrich serving as ranking member. Other members include Sens. Mike Rounds, Susan Collins, Jon Ossoff, Patty Murray, and Jon Husted.
The White House released its full FY2027 budget proposal in April 2026, providing the formal basis for the agencies' requests and the proximate trigger for the hearing. The FY2027 budget appendix covers legislative branch agencies alongside the rest of the federal government, and senators will have had several weeks to review the figures before witnesses appear.
The juxtaposition of a 105 percent increase request from the Architect and a comparatively restrained ask from the Library sets up a hearing where members will need to make distinct judgments about two very different institutional cases, one rooted in deferred infrastructure costs, the other in the political and operational stability of a research institution central to Congress's own work.
