WASHINGTON Lewis "Scooter" Libby, former chief of staff for Vice President Dick Cheney, was found guilty today on 4 counts of perjury and obstruction of justice. Cheney immediately issued a presidential pardon to Libby, voiding his conviction and clearing him of all charges. The pardon was rescinded however after the judge reminded Cheney that he was not the president. Cheney's initial reaction was to ask the judge, "What difference does that make?" After a brief conference with counsel, Cheney told the judge, "I take it back."
