This is a partial list of people pardoned or granted clemency by the President of the United States. The plenary power to grant a pardon or a reprieve is granted to the president by Article II, Section 2, Clause 1 of the Constitution; the only limits mentioned in the Constitution are that pardons are limited to federal offenses, and that they cannot affect an impeachment process: "The president shall ... have power to grant reprieves and pardons for offenses against the United States, except in cases of impeachment".Though pardons have been challenged in the courts, and the power to grant them challenged by Congress, the Court has consistently declined to put limits on the president's discretion. The president can issue a full pardon, reversing a criminal conviction (along with its legal effects) as if it never happened. A pardon can be issued from the time an offense is committed, and can even be issued after the full sentence has been served. The president can issue a reprieve, commuting a criminal sentence, lessening its severity, its duration, or both while leaving a record of the conviction in place. Additionally, the president can make a pardon conditional, or vacate a conviction while leaving parts of the sentence in place, like the payment of fines or restitution.Approximately 20,000 pardons and commutations were issued by U.S. presidents in the 20th century alone. Pardons granted by presidents from George Washington until Grover Cleveland's first term (1885–89) were handwritten by the president; thereafter, pardons were prepared for the president by administrative staff requiring only that the president sign it. The records of these presidential acts were openly available for public inspection until 1934. In 1981 the Office of the Pardon Attorney was created and records from President George H. W. Bush forward are now listed.
