Obama Set to Name Vice Admiral Mike Rogers to Head N.S.A.
The Obama Administration will announce Friday that Vice Admiral Michael S. Rogers will become the new director of the National Security Agency and the commander of the new Pentagon unit that directs the country’s offensive cyberoperations, according to senior administration officials.
Admiral Rogers, a cryptologist by training who has quietly risen to the top of naval intelligence operations, will become the public face of the NSA at a moment that it is caught in the crosshairs of the roiling debate about whether its collection of information about American citizens and foreign leaders has exceeded legal constraints, and common sense.
He will succeed General Keith Alexander, who has served as N.S.A. director for nearly nine years and was the first to direct both the civilian spy agency and the four-year-old Cyber Command.
