President-elect Donald Trump will install William McGinley, a Republican campaign lawyer and former Trump White House adviser, as the White House counsel in the next administration, the Trump-Vance transition said Tuesday.

McGinley will be at the helm in one of the most powerful positions in the West Wing. As White House counsel, McGinley will provide legal advice on policy issues, government ethics, congressional oversight and the powers of the presidency. He will likely be among Trump’s closest advisers.

The White House counsel position does not require Senate confirmation.

“Bill is a smart and tenacious lawyer who will help me advance our America First agenda while fighting for election integrity and against the weaponization of law enforcement,” Trump said in a statement announcing the pick.

McGinley previously served as White House cabinet secretary in Trump’s first administration. In that role, he acted as a liaison between the White House and the Cabinet.

He has also worked at the law firm Holtzman Vogel and has held various positions providing legal advice to the Republican National Committee.
