The US Federal Bureau of Investigation (FBI) has announced that it has begun using polygraph tests to assist in investigations aimed at uncovering the source of information leaks from within the law enforcement agency itself.
"We can confirm that the FBI has begun conducting polygraph tests to identify the source of leaks within the bureau," the FBI's public affairs office said in a statement provided to Reuters.
The Washington Post first reported the FBI's use of the polygraph, better known as a "lie detector."
The administration of Republican President Donald Trump has intensified measures against whistleblowers since Trump returned to office in January.
Last week, the US Department of Justice made it easier for prosecutors investigating media leaks to issue subpoenas to access records and testimony from journalists.
Defense Secretary Pete Hegsett has warned of possible criminal charges against former senior advisers who were fired during the investigation into Pentagon leaks to the media, saying evidence would be turned over to the Justice Department after the investigation is complete. Hegsett's order requiring the investigation left open the possibility of using polygraphs.
Director of National Intelligence Tulsi Gabbard vowed in March to "aggressively pursue those who have recently leaked information" to hold them accountable for unauthorized disclosures.
Last week, Gabaradova said she had forwarded two cases of intelligence community leaks to the Justice Department, adding that a third criminal complaint was in the works.
She also said she was ready to cooperate with the Justice Department and the FBI "to investigate, fire and prosecute" those who leak classified information, whom she called "criminals."
