Bush Orders Enhanced Protection of Classified Information
President Bush ordered members of his cabinet to limit the amount of information shared with Congressional rank and file. According to the article, the Attorney General, the Secretaries of State, Defense, and Treasury, and the Directors of the CIA and FBI, have been ordered to brief only the senior leadership of Congress.
Some reports have indicated that this policy was undertaken in response to a leak of information from a confidential intelligence briefing given to members of Congress.
