FBI starts using polygraph tests in internal leak investigation

The U.S. Federal Bureau of Investigation (FBI) has started using polygraph tests to aid investigations aimed at identifying the source of leaks emanating from within the law enforcement agency.



The bureau's public affairs office said in a statement, "We can confirm the FBI has begun administering polygraph tests to identify the source of information leaks within the bureau."



The Washington Post was the first to report the FBI's use of polygraphs, which are commonly known as "lie detector" tests.



Republican President Donald Trump's administration has been cracking down on people who leak information to journalists since he returned to office in January.



Last week, the U.S. Justice Department made it easier for prosecutors investigating leaks to the news media to subpoena records and testimony from journalists.
