From a newly released GAO report:
The Department of Homeland Security (DHS) and the Department of Defense (DOD) both have systems that track varying levels of detail related to revocations of employees’ security clearances. DHS’s and DOD’s data systems could provide data on the number of and reasons for revocations, but they could not provide some data, such as the number of individuals who received a proposal to revoke their eligibility for access to classified information, which means that the total number of employees affected by the revocation process is unknown.
Inconsistent implementation of the requirements in the governing executive orders by DHS, DOD, and some of their components, and limited oversight over the revocation process, have resulted in some employees experiencing different protections and processes than other employees. Specifically, DHS and DOD have implemented the requirements for the revocation process contained in Executive Orders 12968 and 10865 in different ways for different groups of personnel. Although certain differences are permitted or required by the executive orders, GAO found that implementation by some components could potentially be inconsistent with the executive orders in two areas. As a result, some employees may not be provided with certain information upon which a revocation appeal determination is based, and may not be told that they have a right to counsel.
