The Central Intelligence Agency’s refusal to allow former operative Valerie Plame Wilson to disclose her pre-2002 status as a spy does not violate the First Amendment, a federal appellate court has ruled.

When Ms. Wilson, who had signed a standard secrecy agreement when she joined the agency, tried to publish information about her pre-2002 work as an operative in her memoir “Fair Game: My Life as a Spy, My Betrayal by the White House,” the CIA banned her from publishing what they deemed classified information.
