Plame's Identity Marked As Secret

The paragraph identifying her as the wife of former ambassador Joseph C. Wilson IV was clearly marked to show that it contained classified material at the "secret" level, two sources said. The CIA classifies as "secret" the names of officers whose identities are covert, according to former senior agency officials.
Anyone reading that paragraph should have been aware that it contained secret information, though that designation was not specifically attached to Plame's name and did not describe her status as covert, the sources said. It is a federal crime, punishable by up to 10 years in prison, for a federal official to knowingly disclose the identity of a covert CIA official if the person knows the government is trying to keep it secret.
