President Joe Biden signed an executive order targeting what the White House described as an “epidemic” of violence against Native Americas at this year’s Tribal Nations Summit, the first hosted by the White House since former President Donald Trump’s inauguration in 2017.

Biden announced five new initiatives Monday to mark Native American Heritage Month. The measures include actions aimed at protecting tribal treaty rights, increasing tribal participation in federal lands management, incorporating tribal ecological knowledge into the federal government’s scientific approach, and a 20-year oil and gas leasing ban near New Mexico’s Chaco Canyon, as well as an executive order addressing violence against Native Americans.
