President Joe Biden is running out of time, and so are federal prisoners awaiting clemency for marijuana-related criminal charges stemming from a tough-on-crime approach he helped promote. That fact is on display, literally, on a website launched by the Last Prisoner Project, one of several advocacy groups that have called on the president to make use of his clemency powers before Donald Trump takes office on January 20. In December, the president commuted the sentences for 37 inmates facing the federal death penalty to life in prison.
