Secretary of Transportation Norman Y. Mineta today accepted the resignation of John W. Magaw, the Under Secretary of Transportation for Security. Magaw, who has headed the Transportation Security Administration since January 28, will be replaced by James M. Loy. Upon his retirement as Commandant of the U.S. Coast Guard, Loy was recently named Deputy Under Secretary and Chief Operating Officer of the TSA. “John Magaw is a dedicated public servant with a lifetime of achievements in the law enforcement field, and we all owe him a debt for his role in the start-up phase of TSA,” Secretary Mineta said. “I also appreciate the difficulty of the task. Creating a nationwide system customized to 429 very busy commercial airports is a huge challenge.
