Update: President Trump signed the domestic policy and tax bill into law on Friday, July 4.

“These bills are an affront to our sovereignty, our lands, and our way of life. They would gut essential health and food security programs, roll back climate resilience funding, and allow the exploitation of our sacred homelands without even basic tribal consultation,” said Chalyee Éesh Richard Peterson, president of the Tlingit and Haida in Alaska, in a statement. “This is not just bad policy — it is a betrayal of the federal trust responsibility to tribal nations.”

Tribes across the country are particularly worried about the megabill’s hit to clean energy, complicating the development of critical wind and solar projects. According to the Department of Energy, tribal households face 6.5 times more electrical outages per year and a 28 percent higher energy burden compared to the average U.S. household. An estimated 54,000 people living on tribal lands have no electricity.
