President Joe Biden on Monday announced that he is commuting the sentences of 37 of the 40 people on federal death row, converting their punishments to life imprisonment just weeks before President-elect Donald Trump, an outspoken proponent of expanding capital punishment, takes office.

The decision leaves three federal inmates to face execution. They are Dylann Roof, who carried out the 2015 racist slayings of nine Black members of Mother Emanuel AME Church in Charleston, South Carolina; 2013 Boston Marathon bomber Dzhokhar Tsarnaev; and Robert Bowers, who fatally shot 11 congregants at Pittsburgh’s Tree of life Synagogue in 2018, the deadliest antisemitic attack in U.S history.

“I’ve dedicated my career to reducing violent crime and ensuring a fair and effective justice system,” Biden said in a statement. “Today, I am commuting the sentences of 37 of the 40 individuals on federal death row to life sentences without the possibility of parole. These commutations are consistent with the moratorium my administration has imposed on federal executions, in cases other than terrorism and hate-motivated mass murder.”
