Libby was indicted by a federal grand jury on five felony counts of making false statements to federal investigators, perjury for lying to a federal grand jury, and obstruction of justice for impeding the course of a federal grand jury investigation concerned with the possibly illegal leaking by government officials of the classified identity of a covert agent of the CIA, Valerie Plame Wilson, the wife of former Ambassador Joseph C. Wilson IV. Pursuant to the grand jury leak investigation, Libby was convicted on March 6, 2007, on four counts of perjury, obstruction of justice, and making false statements. He was acquitted of one count of making false statements. Libby was sentenced to 30 months in prison and fined $250,000. The sentence was commuted in June 2007 by President Bush, voiding the prison term. The convictions still stand on the record.
