The former director of the U.S. National Counterterrorism Center (NCTC), Michael Leiter, has joined Skadden, Arps, Slate, Meagher & Flom’s Washington office as a partner in the firm’s national security practice.

The move for Leiter, which Skadden announced on Tuesday, marks the latest in a career that’s included several years in various government roles and in high-ranking corporate positions for software and defense companies. Most recently, Leiter served as an executive at Reston, Virginia-based technology and defense company Leidos Holdings Inc., Skadden said in a statement.
