I’m grateful to the House Committee on Natural Resources for taking an important step to advance my Mammoth Cave National Park Boundary Adjustment Act by conducting today’s legislative hearing.
Brett Guthrie will support the Mammoth Cave National Park Boundary Adjustment Act to expand Mammoth Cave National Park by allowing the park to acquire about 551 acres of land from The Nature Conservancy.

Evidence
The homepage's visible latest-news list on June 11, 2026 shows June 9, June 4, June 4, and May 28 items about ICE funding, a data-center investigation, House appropriations, and an Edmonson County water district event; none mention Mammoth Cave or a boundary-adjustment bill.
The official legislation page only shows 'Sponsored Bills' and 'Co-Sponsored Bills' sections with Congress.gov links in the accessible render; no Mammoth Cave bill title is visible.
Guthrie was elected to the U.S. House of Representatives in 2008. The biography identifies Kentucky's Second District as including Mammoth Cave National Park.
The accessible official legislation page shows headings for Sponsored Bills and Co-Sponsored Bills with Congress.gov links, but the rendered page does not display a Mammoth Cave National Park Boundary Adjustment Act or related bill title.
NPS lists Mammoth Cave National Park as authorized by Congress on May 25, 1926, officially established by Congress on July 1, 1941, and currently totaling 52,830 acres.
NPS says Mammoth Cave National Park was established on July 1, 1941 to preserve cave systems, the Green and Nolin river valleys, and south-central Kentucky hill country.
The NPS release says Mammoth Cave became officially six miles longer because new cave passages were mapped; it discusses Cave Research Foundation survey work, not a land-boundary expansion or Guthrie action.
Assessments
The available evidence confirms Guthrie's relevant federal office and Mammoth Cave's status, but does not verify that he sponsored, cosponsored, voted for, or otherwise materially supported the specific Mammoth Cave National Park Boundary Adjustment Act, nor that the 551-acre Nature Conservancy acquisition/boundary expansion was enacted or completed. Official park statistics and timeline materials do not resolve the specific boundary-adjustment promise. Because the record is insufficient rather than showing a clear failed legislative attempt, the claim remains unresolved.
Available official evidence does not verify that Brett Guthrie sponsored, cosponsored, voted for, or otherwise materially advanced the specific Mammoth Cave National Park Boundary Adjustment Act. The accessible Guthrie House pages provided do not show the bill, and while National Park Service materials show later Mammoth Cave updates and current park information, they do not tie Guthrie to the 551-acre boundary-adjustment measure or confirm that the promised support occurred. Because the record here does not establish either Guthrie's concrete support or enough candidate credit for any later outcome, the promise is best scored as unresolved rather than delivered or never.
