Attendees take pictures and video as U.S. President Barack Obama participates in the annual White House Tribal Nations Conference in Washington November 5, 2015. Obama courted the American Indian vote as a first-time White House candidate in 2008. He became an honorary member of a tribe in Montana, the Crow Nation, and took on a native name: Black Eagle, which means "one who helps all people of this land." REUTERS/Jonathan Ernst
