Director of national intelligence wants to widen "counterintelligence polygraph"

Move would be aimed at workers with top secret clearance

Questions would include whether worker has passed info to journalists, for example

Washington CNN  — 

Director of National Intelligence James Clapper wants more government employees to be subject to an enhanced lie detector test as a deterrent to leaking classified information, an intelligence source told CNN Thursday.

As he briefs top intelligence lawmakers who are outraged over a series of recent leaks of classified information, Clapper wants to widen the numbers of people across government agencies who would be required to take the “counterintelligence polygraph,” the source said. The move would be aimed at government employees who hold top secret clearance.

As of now, not everyone with that clearance level is required to take this specific polygraph, which, the source said, would have questions added such as whether the employee has passed information to journalists.
