WASHINGTON — President Barack Obama cut short on Tuesday the sentences of 111 federal inmates in another round of commutations for those convicted of nonviolent drug offenses.

Obama has long called for phasing out strict sentences for drug convictions, arguing they lead to excessive punishment and incarceration rates unseen in other developed countries.

White House Counsel Neil Eggleston said the commutations underscored the president’s commitment to using his clemency authority to give deserving individuals a second chance. He said that Obama has granted a total of 673 commutations, more than the previous 10 presidents combined. More than a third of the recipients were serving life sentences.

“We must remember that these are individuals — sons, daughters, parents, and in many cases, grandparents — who have taken steps toward rehabilitation and who have earned their second chance,” Eggleston said. “They are individuals who received unduly harsh sentences under outdated laws for committing largely nonviolent drug crimes.”

Eggleston says he expects Obama to continue using his clemency authority through the end of his administration.
