The Defense Counterintelligence and Security Agency (DCSA) bid farewell to Director William K. Lietzau in a ceremony today at the National Museum of the Marine Corps.  The event reflected on Lietzau's tenure at DCSA and the role of the agency in protecting national security.  As part of the ceremony, transfer of authority of the agency was transferred to Daniel J. Lecce, now acting director of DCSA.
 
In 2019, Lietzau joined an agency that had just merged several organizations into one and oversaw the implementation of centralized critical national security enterprise capabilities for personnel security, industrial security, counterintelligence, and security training.  During his time with the agency, he spearheaded the agency's strategic transformation and evolution into the Government's premier organization for vetting, industrial engagement, counterintelligence support, and security training with a workforce of approximately 12,000 federal and contract support personnel worldwide.  Additionally, Lietzau has been supervising the development and deployment of an end-to-end national-level Information Technology infrastructure designed to support the security enterprise.
