Oklahoma tribes said Trump administration proposals to revise the National Historic Preservation Act could put ancestral lands in Ohio at risk.
The tribes argue the legal changes would weaken protections for historic sites significant to Native nations, extending the threat beyond Ohio to tribal places across the country.
Ohio is the immediate flashpoint because tribes based in Oklahoma still regard sites there as ancestral lands tied to their history and cultural identity.
The dispute broadens scrutiny of the administration's preservation agenda, with tribes framing the proposed NHPA changes as a national risk to consultation and site protection.
