President Barack Obama has snagged two aides to Senate Judiciary Chairman Patrick Leahy (D-Vt.) to serve in his White House counsel’s office. Mary DeRosa, who was Leahy’s chief counsel for national security, will be deputy counsel to the president for national security affairs and legal adviser to the National Security Council. Susan Davies, a veteran Judiciary Committee staffer who most recently served as general counsel and chief counsel for intellectual property, will be an associate counsel in the White House office. Obama also named Daniel Meltzer to be principal deputy to White House Counsel Gregory Craig. Meltzer is the Story professor of law at Harvard Law School and the vice dean for physical planning.
