..... "First, I want to make some general comments about pardons and commutations of sentences. Article II of the Constitution gives the president broad and unreviewable power to grant "Reprieves and Pardons" for all offenses against the United States. The Supreme Court has ruled that the pardon power is granted "[t]o the [president] . . ., and it is granted without limit" (United States v. Klein). Justice Oliver Wendell Holmes declared that "[a] pardon . . . is . . . the determination of the ultimate authority that the public welfare will be better served by [the pardon] . . ." (Biddle v. Perovich). A president may conclude a pardon or commutation is warranted for several reasons: the desire to restore full citizenship rights, including voting, to people who have served their sentences and lived within the law since; a belief that a sentence was excessive or unjust; personal circumstances that warrant compassion; or other unique circumstances."
The exercise of executive clemency is inherently controversial. The reason the framers of our Constitution vested this broad power in the Executive Branch was to assure that the president would have the freedom to do what he deemed to be the right thing, regardless of how unpopular a decision might be. Some of the uses of the power have been extremely controversial, such as President Washington's pardons of leaders of the Whiskey Rebellion, President Harding's commutation of the sentence of Eugene Debs, President Nixon's commutation of the sentence of James Hoffa, President Ford's pardon of former President Nixon, President Carter's pardon of Vietnam War draft resisters, and President Bush's 1992 pardon of six Iran-contra defendants, including former Defense Secretary Weinberger, which assured the end of that investigation."
