Pardons and Clemency
The pardon is one of the few presidential powers with almost no check from another branch.
The Constitution lets the President forgive federal crimes, shorten sentences, and cancel fines — for any reason, at any time after the offense. The power was meant as a safety valve for mercy and national reconciliation. Its limits are few but real: it covers only federal crimes, and it can’t stop an impeachment.
The President … shall have Power to grant Reprieves and Pardons for Offences against the United States, except in Cases of Impeachment.
U.S. Constitution, Article II, Section 2
What the Power Does
Clemency can be granted before charges, during a prosecution, or after a conviction. It restores rights lost through a conviction and removes federal punishment, but it doesn’t erase the historical record or bind states, which prosecute most crimes. Alexander Hamilton defended the power in Federalist No. 74 as a way to temper justice with mercy and to calm moments of national unrest.
Forms of Clemency
Pardon
Full forgiveness of a federal offense and its legal consequences.
Commutation
Shortens or ends a sentence while leaving the conviction in place.
Reprieve
Temporarily delays a punishment, such as an execution.
Remission
Cancels fines or forfeitures.
Amnesty
Clemency for a whole group — as with Jimmy Carter’s 1977 amnesty for Vietnam-era draft evaders.
Limits
Federal only
State crimes are beyond the President’s reach.
Not impeachment
A pardon can’t block or undo an impeachment.
Untested edges
Whether a President can pardon himself has never been decided by a court.
How Requests Are Handled
Most petitions go to the Office of the Pardon Attorney at the Justice Department, which reviews them and makes recommendations. Presidents don’t have to use that process, and many high-profile grants have bypassed it. Grants are public and listed on the Justice Department’s website.
Pardons That Made History
Gerald Ford’s 1974 pardon of Richard Nixon, before any charges were filed, is the most famous and among the most debated. Andrew Johnson pardoned former Confederates; Presidents of both parties have issued controversial end-of-term grants, including preemptive pardons for relatives and former officials. Because the power is nearly absolute, its main check is political: voters, history, and public reaction.
