On January 20, outgoing President Joseph Biden commuted the sentence of Leonard Peltier, who is age 80. See this story.
Peltier was the presidential nominee of the Peace & Freedom Party in 2004. The party nominated him to make a statement that he had been unjustly convicted. Pelter was also the original vice-presidential nominee of the Party for Socialism and Liberation in 2020. That party similarly wanted to highlight the injustice of his treatment. He resigned from the 2020 ticket, allegedly for health reasons, but actually because his attorneys believed his candidacy would damage his chances of leniency from President Trump.
