Article II, Section 2, Clause 1 of the US Constitution grants the President the power to grant reprieves and pardons for federal offenses.

A presidential pardon can release a convicted criminal from prison, expunge their criminal record, and restore their civil rights.

There is no clear consensus on whether a president can pardon themselves. The issue has never been tested in court.

Individual pardons are the most common type of presidential pardon. They are granted to a single individual for a specific offense.

A conditional pardon is a pardon that is granted on the condition that the recipient meets certain requirements, such as paying restitution to the victim or completing a period of probation.

An absolute pardon is a pardon that is granted without any conditions. It completely wipes out the conviction and restores the recipient's civil rights.

George Washington was the first president to grant a presidential pardon. He pardoned two men who had been convicted of counterfeiting.

Jimmy Carter granted the most presidential pardons, with a total of 534.

The pardon of Richard Nixon by Gerald Ford is considered to be the most controversial presidential pardon in history. Nixon had resigned from office in disgrace after the Watergate scandal, and Ford's pardon prevented him from being prosecuted for any crimes.

Presidential pardons are still being granted by the president, although they are now more rare than they used to be.
