The FBI has stepped up its use of polygraph tests to investigate possible leaks and check employee loyalty to Director Kash Patel.

Under Kash Patel's leadership, the FBI began using polygraph tests to determine who disclosed information about its unusual requests, including the service weapon request. The move reflects a heightened concern for information control and employee loyalty, prompting criticism from former officials who view the practices as inappropriate and politicized. Many senior employees feared reprisals, leading to significant departures from the office.
