The Senate proposal, which could greatly affect outdoor recreation in the West, is facing strong pushback from conservationists, Democrats and MAGA supporters.

Proponents say the land would be used for much-needed housing, but environmental groups say eligible areas could include those treasured by communities in the Mountain West.

No more than 3 million acres could be sold, but a conservation advocacy group says determined the scale and range of lands that meet the criteria for sale in the latest reconciliation bill.
