On Monday, President Barack Obama pardoned 78 people and commuted the sentences of 153 others, setting a single-day record for the use of presidential clemency power.

With 32 days left in his administration, he’s pardoned a total of 148 prisoners and commuted the sentences of 1,176 federal inmates.

However, the president has not addressed a backlog of clemency cases at the Office of the Pardon Attorney where 1,937 pardon petitions remain pending along with 13,042 applications for commutations, USA Today reports.

“We need the president to pick up the pace of commutations before he leaves office," Michael Collins of the Drug Policy Alliance told the news outlet. “He is to be applauded for his actions thus far, but we know that the next occupant of the White House is unsympathetic to the cause of mass incarceration, and to the plight of those serving unjust sentences in federal prison.”
