Title 10 › Subtitle Subtitle A— General Military Law › Part II— PERSONNEL › Chapter 80— MISCELLANEOUS INVESTIGATION REQUIREMENTS AND OTHER DUTIES › § 1564a
The Secretary of Defense can run a program that gives counterintelligence polygraph (lie detector) tests to certain people who work for or with the Department of Defense. That includes military and civilian DoD workers, defense contractors, people assigned or detailed to DoD, applicants for DoD jobs, and U.S. nationals who are also citizens of another country when they need access to classified information. The tests can be used for people whose jobs involve top secret or special access program information, or who help intelligence or military missions where a leak could endanger lives, destroy unique intelligence sources or methods, or damage critical technology or plans. The program does not apply to people assigned to the CIA or NSA, people working where sensitive cryptographic material is handled, or certain DoD reconnaissance intelligence offices and their contractors. All polygraph exams must follow laws and regulations and include protections set by the Secretary. People must be told about the test and its purpose, give consent before testing, and may consult a lawyer. Questions must relate to the issue being investigated. Tests can be for initial or random checks of eligibility, to resolve or rebut serious security concerns, for temporary clearance in urgent cases, or to help foreign preference/ influence investigations (see part 147 of title 32). The Secretary must monitor how polygraphs are used, share information with the congressional defense committees, and run ongoing research on test validity, countermeasures, and new techniques and equipment.
