A year after former President Joe Biden spared 37 prisoners on federal death row from execution by reducing their sentences to life in prison, the Trump administration is making good on its promise to treat them as harshly as possible anyway.

Ten of the prisoners were transferred to one of the most restrictive maximum-security prisons in the U.S., an infamous facility in Colorado nicknamed "the Alcatraz of the Rockies" where every prisoner is kept in solitary confinement. Two were taken to states where prosecutors have pledged to seek the death penalty against them again, in state court. Two others face death penalty charges in Florida. And the rest are stuck in limbo, having been told to expect a move to the Colorado prison, named ADX Florence, at any moment.
