October 18, 2001: Paul Wolfowitz Issues Memo Urging Secrecy Among Defense Department Staff

Deputy Defense Secretary Paul Wolfowitz issues a memorandum to senior officials throughout the Defense Department stating that, following President Bush’s declaration of a national emergency on September 14, Defense Department employees should exercise great caution whenever discussing information relating to their department’s work. The memo instructs: “Do not conduct any work-related conversations in common areas, public places, while commuting, or over unsecured electronic circuits. Classified information may be discussed only in authorized spaces and with persons having a specific need to know and the proper security clearance. Unclassified information may likewise require protection because it can often be compiled to reveal sensitive conclusions. Much of the information we use to conduct [the department]‘s operations must be withheld from public release because of its sensitivity. If in doubt, do not release or discuss official information except with other [Defense Department] personnel.” According to the memo, “the security of information critical to the national security will remain at risk for an indefinite period.” [US Department of Defense, 10/18/2001; Washington Times, 10/23/2001]
