WASHINGTON ― With literally minutes left in his presidency, Joe Biden on Monday granted clemency to Leonard Peltier, the ailing Native American rights activist whom the U.S. government put in prison nearly 50 years ago after a trial riddled with misconduct and lies.

Peltier has been in prison ever since the federal government accused him of murdering two FBI agents in a 1975 shoot-out on Pine Ridge Reservation in South Dakota.
