By the end of his presidency on January 20, 2017, Barack Obama had exercised his constitutional power to grant executive clemency—that is, "pardon, commutation of sentence, remission of fine or restitution, and reprieve"—to 1,927 individuals convicted of federal crimes. Of the acts of clemency, 1,715 were commutations (including 504 life sentences) and 212 were pardons. Most individuals granted executive clemency by Obama had been convicted on drug charges, and had received lengthy and sometimes mandatory sentences at the height of the War on Drugs.
Obama holds the record for the largest single-day use of the clemency power, granting 330 commutations on January 19, 2017, his last full day in office. He also has issued more commutations than the past thirteen presidents combined.
The pardon powers of the President are outlined in Article Two of the United States Constitution (Section 2, Clause 1), which provides:
The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States; he may require the Opinion, in writing, of the principal Officer in each of the executive Departments, upon any Subject relating to the Duties of their respective Offices, and he shall have Power to grant Reprieves and Pardons for Offenses against the United States, except in Cases of Impeachment.
This is a partial list of people pardoned or granted clemency by a United States president, ordered by date of pardon or commutation. For an updated list, see U.S. Department of Justice.
