Title 10 › Subtitle A — General Military Law › PART II — PERSONNEL › CHAPTER 80 — MISCELLANEOUS INVESTIGATION REQUIREMENTS AND OTHER DUTIES › § 1564a
The Defense Secretary can run a counterintelligence polygraph program for certain people who work for or with the Department of Defense. It covers military and civilian DoD employees, defense contractors, people assigned or detailed to DoD, and applicants for DoD jobs. It also covers U.S. citizens who are also citizens of another country if they need access to classified information. The program does not apply to people assigned to the Central Intelligence Agency or the National Security Agency, to those working where sensitive cryptographic data is handled, or to some DoD reconnaissance intelligence offices and their contractors. Polygraph tests must follow all laws and Defense rules. They can be used before hiring, sometimes at random later, with a person’s consent to clear up serious security concerns, to allow temporary access in urgent cases, or to check foreign-influence risks for dual nationals. People must be told about the test and its purpose, must agree to take it, can talk to a lawyer, and can only be asked relevant questions. The Defense Secretary must monitor how polygraphs are used and share information with congressional defense committees. The Secretary must also run ongoing research on polygraph accuracy, ways people try to trick polygraphs, and better testing methods and tools.
