Alexandria, VA (CNN) - A former CIA officer pleaded not guilty to charges of giving reporters classified information and lying to a CIA review board.

Investigators say Kiriakou gave classified information to journalists and lied to a CIA review board about material in a book he wrote.

Kiriakou worked for the CIA from 1990 to 2004.

The five-count indictment includes three charges under the Espionage Act, claiming Kiriakou revealed national defense information to individuals not authorized to receive it, specifically, reporters.

He faces a maximum of 45 years in prison if convicted on all charges.
