President Joe Biden is commuting the sentences of roughly 1,500 people who were released from prison and placed on home confinement during the coronavirus pandemic and is pardoning 39 Americans convicted of nonviolent crimes. It's the largest single-day act of clemency in modern history.

The commutations announced Thursday are for people who have served out Home confinement sentences for at least one year after they were released. Prisons were uniquely bad for spreading the virus and some inmates were released in part to stop the spread. The second largest single-day act of clemency was by Barack Obama, with 330, shortly before leaving office in 2017. “America was built on the promise of possibility and second chances,”Biden said in a statement. “As president, I have the great privilege of extending mercy to people who have demonstrated remorse and rehabilitation, restoring opportunity for Americans to participate in daily life and contribute to their communities, and taking steps to remove sentencing disparities for non-violent offenders, especially those convicted of drug offenses.”

The clemency follows abroad pardon for his son Hunter, who was prosecuted for gun and tax crimes. Biden is under pressure from advocacy groups to pardon broad swaths of people.
