The president has used his broad pardon powers rarely during seven years in office, granting 157 pardons out of 2,064 petitions, and only six of 7,707 requests for commutations, according to an analysis by former Justice Department lawyer Margaret C. Love.
BUT,,,
Bush has not mentioned pardons often, but in a statement released in July 2007, he said "the Constitution gives the President the power of clemency to be used when he deems it to be warranted."
President Bill Clinton prompted congressional and federal investigations by pardoning 140 people, including his brother, former Arkansas real estate partner Susan McDougal and fugitive financier Marc Rich. White House officials and former deputy attorney general Eric H. Holder Jr., now a contender for attorney general under President-elect Barack Obama, testified about the last-minute pardons in fiery congressional hearings.
