On December 29,2005, the President approved a revision of the Adjudicative Guidelines for Determining Eligibility for Access to Classified Information. The revised guidelines were distributed as an attachment to a memorandum from Stephen J. Hadley, Assistant to the President for National Security Affairs,
addressed to William Leonard, Director of the Information Security Oversight Office. In his memorandum, Mr. Hadley instructed Mr. Leonard to circulate the revised guidelines for immediate implementation by all agencies that grant security clearances. Mr. Hadley further emphasized that all agencies must honor clearances granted under the new guidelines, consistent with Executive Order (E.O.) 12968 and the December 12,2005, memorandum on reciprocity issued by Clay Johnson, Deputy Director for Management, Office of Management and Budget.
