Former President Joe Biden commuted the life sentence of Indigenous activist Leonard Peltier, who had been imprisoned for nearly 50 years, on Jan. 20.

The commutation will allow Peltier, who has long maintained his innocence in the killing of two FBI agents, to spend his remaining days in home confinement.

The ailing Native American rights activist has been in prison for nearly 50 years after the U.S. government lied to put him there.
