FBI Director Kash Patel has significantly increased the use of polygraph tests within the bureau, reportedly to identify personnel who may be leaking information or expressing dissent regarding his leadership. These tests, often deemed unreliable for court proceedings, are being administered to current and former staff, including members of his security detail and IT personnel. The intensified polygraph examinations appear to be a response to multiple media reports that have raised questions about Patel's leadership.
The polygraph examinations are targeting individuals who may have communicated with reporters or spoken negatively about Director Patel or his deputy, Dan Bongino. Sources indicate that dozens of FBI employees have undergone these tests. Some questioning has specifically focused on whether individuals have made disparaging remarks about Patel.
This development has drawn criticism, with former officials suggesting it signals a troubling shift from national security focus to policing personal allegiance. One notable instance involved a former top FBI agent, Michael Feinberg, who reportedly resigned after being threatened with a polygraph due to his association with Peter Strzok, a former counterintelligence official dismissed from the Bureau. In another reported incident, FBI Director Patel allegedly threatened agents with polygraphs and prosecution over a missing bottle of bourbon from his personal collection.

The increased reliance on polygraphs, traditionally used for national security vetting or serious internal investigations, has sparked controversy. Critics argue that Patel, alongside Deputy Director Dan Bongino, is implementing a top-down restructuring aimed at purging perceived ideological opponents and consolidating control.
During a Senate Judiciary Committee oversight hearing on September 16, 2025, Senator Durbin questioned Director Patel about "partisan and incompetent management" and "unprecedented purging of highly qualified FBI officials." Patel reportedly evaded direct answers to these inquiries.
The FBI has not officially denied the increased use of polygraphs but has stated, through Deputy Director Dan Bongino, that "no amount of hit pieces on him and Kash Patel can stop the purgation that they have taken up." This suggests a deliberate effort by leadership to reshape the agency's personnel and operations.

Historically, polygraph tests within the FBI have been reserved for specific purposes, such as national security vetting and security clearance processes. Their use for internal investigations, especially concerning expressions of opinion or criticism of leadership, represents a departure from established norms. The reliability of polygraphs themselves has been a subject of debate, with legal bodies often deeming them inadmissible as evidence in criminal trials. However, federal security agencies have commonly employed them for internal reviews.
Director Patel, who lacks prior FBI experience, has been a prominent figure in various roles within the Trump administration. His tenure as FBI Director has been marked by reports of significant organizational changes and a focus on perceived loyalty. This intensified use of polygraphs appears to be part of a broader effort to manage information flow and address internal dissent, according to various sources familiar with the matter.
