President-elect Donald Trump on Wednesday announced that GW Law alum William McGinley, who he tapped last month for White House counsel, will instead serve as counsel to a new Department of Government Efficiency.

Trump replaced McGinley with David Warrington, his campaign’s general counsel, weeks after he initially selected the alum for the role, according to his post on Truth Social, a social media company owned by Trump Media & Technology Group. He said McGinley will serve as counsel to the new Department of Government Efficiency, a planned presidential advisory commission led by Elon Musk and Vivek Ramaswamy to provide recommendations for government leaders to implement.

“Bill is a great addition to a stellar team that is focused on making life better for all Americans,” Trump wrote on Truth Social. “He will be at the forefront of my Administration’s efforts to make our Government more efficient and more accountable.”

McGinley did not immediately return a request for comment on the change in roles.

Boris Epshteyn, one of Trump’s aides who has been accused by several people trusted by Trump of seeking money to promote potential appointees in the new administration, pushed for McGinley to be White House Counsel. Trump directed his team, which includes Warrington, to carry out a review of Epshteyn’s alleged asks for payment in exchange for appointment support, according to the New York Times.

McGinley served as White House cabinet secretary in the first half of Trump’s first term in office, where he acted as a liaison between the White House and the Cabinet. McGinley left the position in July 2019 and has been a partner at the Washington-based law firm Holtzman Vogel.

McGinley graduated from GW Law in 1997 and served as an adjunct professor from 2016 to 2017, where he taught campaign finance law, according to his LinkedIn.
