The dispute centers on Kendall’s public assessments of a Boeing 747-8 aircraft donated by Qatar and being converted for potential use as a presidential aircraft. In media interviews and reports in July, Kendall questioned whether the aircraft could be equipped quickly enough with the communications, security and other systems required for presidential operations, arguing that significant modifications could take years. The Trump administration has defended the aircraft’s security and capabilities, while the broader controversy has included scrutiny of how information about the plane was reported and the administration’s efforts to investigate leaks of classified material. Kendall’s clearance revocation adds a new dimension to that dispute by formally restricting the former senior defense official’s access to classified information.
