WASHINGTON (AP) -- Former White House aide Lewis Libby has been sentenced to two and a-half years in prison for perjury and obstruction of justice in the CIA leak case.
Libby stood calmly as a federal judge said the evidence had overwhelmingly proven his guilt. The judge said people in positions like the one Libby held -- as chief of staff to Vice President Cheney -- "have a special obligation to not do anything that might create a problem."
Libby was convicted in March of lying and obstructing an investigation into the 2003 leak of C-I-A operative Valerie Plame's identity.
Libby has maintained his innocence and is appealing his conviction.
