President Bush's decision to commute the sentence of former White House aide, I. Scooter Libby, this week ended a four-year controversy.
It all started in July 2003 when longtime syndicated columnist Robert Novak revealed the identity of a CIA operative, Valerie Plame. Discovering who leaked that sensitive information — an illegal act — turned into a lengthy criminal investigation. It ended when Scooter Libby was sentenced to 2 1/2 years in jail.
After Libby's sentencing, Novak called on Mr. Bush to pardon Scooter Libby.
Novak talks to Alex Cohen.
