Mr. Trump said that, beginning September 1, Mr. Scharf will be replacing David Warrington, who will be leaving the administration to join the private sector. Mr. Trump noted that Mr. Scharf previously served as a federal prosecutor and represented him in a number of cases, including at the Supreme Court. “Will Scharf will do a great job as White House Counsel!” The White House counsel’s job is to advise on legal and policy questions related to the presidency. The project is already well on its way and has begun to rise above ground on the east side of the White House.
