USGS nominee pledges to protect data and expand mapping as senators press on proposed cuts and past statements
Summary
Dr. Ned Mamula, President Trump's nominee to lead the U.S. Geological Survey, pledged to prioritize geologic mapping, data preservation and mission continuity if confirmed. Senators raised concerns about proposed budget cuts to USGS programs, potential politicization of agency science, and the importance of water and critical‑minerals data.
Dr. Ned Mamula, nominated to be director of the U.S. Geological Survey (USGS), told the Senate Energy and Natural Resources Committee on May 13 that he would "uphold the USGS mission" and make geologic mapping and long‑term data integrity a priority if confirmed.
During questioning, several senators pressed Dr. Mamula about the agency’s role in critical‑minerals assessments and long‑term water data. Senator John Hickenlooper highlighted the importance of USGS water science to drought‑prone western states and asked whether Mamula would prioritize maintaining and expanding the agency’s measurement systems. Mamula responded, "If confirmed ... this has to be a priority and I'm going to make it my business to make sure it is," and noted the agency is "a data factory" whose output should be preserved and digitized.
Ranking Member Martin Heinrich warned that the USGS "must remain nonpartisan and independent," and said the integrity of its science is essential for decisions across government and industry. Heinrich also referenced past remarks from Mamula that raised questions about whether he would preserve the agency’s impartial approach to conservation and public‑land withdrawals.
Senator Angus King and others pressed Mamula on reports that the president’s fiscal 2026 budget proposes large reductions to USGS funding, including cuts to biological research and water‑science centers. Mamula said he would review the budget details and make the agency’s priorities a focus from day one. Senator Catherine Cortez Masto emphasized the importance of USGS grants and cooperative programs with state geological surveys and universities for mapping and critical‑minerals research.
Background and significance: Mamula emphasized the historical role of the USGS and framed mapping and resource assessment as central to national security and economic stability. He cited the U.S. Geological Survey Organic Act and described mapping as essential before exploration and production of energy and mineral resources.
What was not resolved: The hearing did not change appropriations. Several senators voiced concern about proposed budget cuts and asked the nominee to commit to protecting key scientific programs; Mamula pledged review and support but deferred specific budget decisions to the appropriations process.
Ending: Mamula told the committee he is "ready for this next assignment" and that he would "uphold the USGS mission" if confirmed. Senators said they would submit follow‑up questions for the record.
