President Trump took the extraordinary step Friday of overruling the judgment of his predecessor, George W. Bush, and granting a pardon to I. Lewis Libby Jr., who served as chief of staff to Vice President Dick Cheney.
Libby, known as "Scooter," was convicted of perjury and obstruction of justice in 2007 in connection with the leak of a CIA officer's identity. Bush had commuted Libby's sentence but did not issue a full pardon.
