provide that, except as may be permitted by the President, no employee in the executive branch of Government may be given access to classified information by any department, agency, or office of the executive branch of Government unless, based upon an appropriate background investigation, such access is determined to be clearly consistent with the national security interests of the United States;

establish uniform minimum requirements governing the scope and frequency of background investigations and reinvestigations for all employees in the executive branch of Government who require access to classified information as part of their official responsibilities;

provide that all employees in the executive branch of Government who require access to classified information shall be required as a condition of such access to provide to the employing department or agency written consent which permits access by an authorized investigative agency to relevant financial records, other financial information, consumer reports, travel records, and computers used in the performance of Government duties, as determined by the President, in accordance with section 3162 of this title, during the period of access to classified information and for a period of three years thereafter;

provide that all employees in the executive branch of Government who require access to particularly sensitive classified information, as determined by the President, shall be required, as a condition of maintaining access to such information, to submit to the employing department or agency, during the period of such access, relevant information concerning their financial condition and foreign travel, as determined by the President, as may be necessary to ensure appropriate security; and

establish uniform minimum standards to ensure that employees in the executive branch of Government whose access to classified information is being denied or terminated under this subchapter are appropriately advised of the reasons for such denial or termination and are provided an adequate opportunity to respond to all adverse information which forms the basis for such denial or termination before final action by the department or agency concerned.

Subsection (a) shall not be deemed to limit or affect the responsibility and power of an agency head pursuant to other law or Executive order to deny or terminate access to classified information if the national security so requires. Such responsibility and power may be exercised only when the agency head determines that the procedures prescribed by subsection (a) cannot be invoked in a manner that is consistent with the national security.

Upon the exercise of such responsibility, the agency head shall submit a report to the congressional intelligence committees.
