Donald Vieira, a former chief of staff in the U.S. Department of Justice’s national security division who joined Wilson Sonsini Goodrich & Rosati in 2011, has left the firm’s office in the nation’s capital for Skadden, Arps, Slate, Meagher & Flom.

A Friday evening phone call and email to Vieira were not immediately returned by the time of this story. While not yet listed on Skadden’s website, Vieira has updated his registry with The District of Columbia Bar to reflect his new status at Skadden.
