The clemency action applies to all federal death row inmates except three convicted of terrorism or hate-motivated mass murder: Dzhokhar Tsarnaev, convicted of carrying out the 2013 Boston marathon bombing attack; Dylann Roof, who shot dead nine Black church members in Charleston, South Carolina, in 2015; and Robert Bowers, who stormed a synagogue in the heart of Pittsburgh’s Jewish community and killed 11 worshippers in 2018.
