WASHINGTON--(BUSINESS WIRE)--Sidley Austin LLP is pleased to announce that Brian Morrissey, who previously served in senior roles at the U.S. Department of the Treasury and the U.S. Department of Justice, has rejoined the firm’s White Collar: Government Litigation and Investigations practice as a partner in Washington, D.C.

He is also a former law clerk to U.S. Supreme Court Justice Clarence Thomas.
