Director of National Intelligence Tulsi Gabbard has instructed U.S. intelligence agencies to evaluate the feasibility of conducting random polygraph tests for employees and contractors, according to officials familiar with the directive.

The proposed tests would include questions aimed at determining whether individuals have leaked classified information to the media, part of a broader effort to strengthen internal security and prevent unauthorized disclosures, Just the News reported.

The directive, issued within the past month, follows similar actions by multiple federal agencies that have implemented polygraph testing to help identify unauthorized leaks to the media.

The move also comes in the wake of former FBI Director James Comey’s indictment by a federal grand jury last month on charges that he made false statements to Congress after denying that he leaked information to reporters.

Two sources told CBS News that Gabbard’s memo specifically highlights polygraph questions related to potential media leaks and indicates that such testing will become more frequent and routine across the intelligence community
