John Guandolo is an American security consultant, author and former FBI agent. A U.S. Naval Academy graduate and Marine Corps veteran, he provides training for citizens, local officials and law enforcement.
Case
Laura Loomer claimed an FBI source said Zohran Mamdani was denied a security clearance over possible terrorist contacts. Mamdani later announced he had his clearance, and Loomer repeated her allegations. What does the public record establish?
Role at the time: Security consultant and former FBI agent, commenting in a personal capacity
Response to this claim
The FBI denied Zohran Mamdani a security clearance because of possible direct communication with terrorist organizations and would not grant him one.
“Mamdani is a jihadi. Of course he is talking to terrorists.”
Guandolo directly supports the terrorist-contact premise of Loomer's allegation. His former FBI employment does not make this post a statement by the bureau or evidence of its clearance decision.
