Why It Matters

The House Appropriations Committee is set to mark up the FY2027 Commerce, Justice, Science, and Related Agencies bill on Wednesday, putting Congress on a direct collision course with the White House over funding for NASA, the National Science Foundation, NOAA, and federal law enforcement.

The Republican-led subcommittee has already rejected the Trump administration's proposed 23 percent cut to NASA, advancing a $24.4 billion alternative, and voted to cut NSF funding by 20 percent. The full committee must now ratify or revise those numbers. These decisions will shape federal investment in science, space, and law enforcement for the coming fiscal year.

The markup arrives as commercial space companies, law enforcement advocates, and scientific research organizations have collectively poured millions of dollars into lobbying Congress on the bill's provisions. At stake are funding levels for agencies that touch everything from hurricane forecasting to violent crime investigations to lunar exploration.

NASA

The most politically charged line item heading into the full committee markup is NASA. The Trump administration's FY2027 budget request proposed $18.8 billion for the agency, a 23 percent reduction from FY2026 enacted levels. The Republican-led CJS subcommittee rejected that figure and advanced a $24.4 billion plan instead.

The administration's original request had included a proposed $3.4 billion cut to science missions, a $1.1 billion reduction in International Space Station funding, and a $143 million cut to the Office of STEM Engagement, according to reporting by Eos.

Commercial space companies have been active on Capitol Hill throughout this cycle. Impulse Space leads lobbying expenditures on NASA-related issues, with more than $1.1 million in filings tied to NASA reauthorization and appropriations.

Relativity Space spent $470,000 in the first quarter of 2026 alone on issues related to commercial space launch and CJS appropriations. Axiom Space has logged $150,000 in first-quarter 2026 filings specifically referencing the FY2027 Commerce, Justice, Science appropriations bill.

Intuitive Machines, which operates NASA's Commercial Lunar Payload Services program, has lobbied on FY2026 and FY2027 CJS appropriations, focusing on lunar payload services and satellite servicing technologies.

NSF and NOAA

The subcommittee voted to cut the National Science Foundation's budget by 20 Percent for FY2027, a figure that Scientific American characterized as lawmakers rejecting the Trump administration's even deeper proposed reductions. NOAA would see a five percent cut under the subcommittee's bill.

The NOAA funding debate carries particular weight given the administration's broader rollback of climate and weather science programs. Multiple organizations have been lobbying on NOAA's budget, including filings focused on the NOAA Organic Act and weather bill reauthorization, the National Mesonet Program, and phased array radar research. The National Center for Atmospheric Research has also been active, with filings referencing FY2026 and FY2027 issues relating to atmospheric research.

NSF grant terminations (particularly those tied to DEI-related and social science research) have been a running controversy in 2026, making the foundation's funding levels one of the more politically loaded decisions the full committee will face.

Justice Department

The Department of Justice enters the FY2027 markup cycle in a constrained position. The ATF absorbed a $40 million, 2.5 percent cut under the FY2026 DOJ spending bill, and the ATF director nominee testified in February 2026 that those reductions were damaging operations. The DOJ's FY2027 budget and performance summary has been published, setting the baseline for what the committee will negotiate.

Law enforcement advocacy organizations have been lobbying on specific Justice Department programs. Multiple filings reference FY2027 appropriations for the Bureau of Alcohol, Tobacco, Firearms, and Explosives and DOJ grant programs, with a particular focus on enhancing the National Integrated Ballistic Information Network for use by state and local law enforcement in violent crime investigations. Separate filings reference law enforcement DNA funding under the CJS bill.

DOGE-related cuts to DOJ and the FBI have added a layer of tension to the markup. A former FBI special agent told CNN that lawmakers should examine whether DOGE's approach had created "any negative implications from what was done through that process (and) if it's having any negative impact on any aspect of our government, including our national security and national defense." Democratic members of the Appropriations Committee are expected to use the markup as a venue to challenge executive branch spending decisions made outside the congressional appropriations process.

The Committee and the Process

Tom Cole (R-OK) chairs the House Appropriations Committee and will preside over Wednesday's markup. Rosa DeLauro (D-CT) serves as Ranking Member and has been a consistent critic of the administration's approach to agency funding.

The subcommittee markup (the immediate precursor to Wednesday's session) was completed on April 30, 2026, when the House Appropriations Committee released the bill text ahead of that session.

The FY2026 CJS bill, which the Senate passed 82-15, provided $79.7 billion in discretionary funding. The FY2027 markup will be measured against that baseline, with the NASA funding disagreement between Congress and the White House representing the sharpest divergence between the two branches as the bill moves forward.
