Marcus Christian is a Washington partner in Mayer Brown's Litigation & Dispute Resolution practice and White Collar Defense & Compliance group. Previously, he was the executive assistant United States attorney at the US Attorney's Office for the Southern District of Florida, the third-highest ranking position in one of America's largest and busiest offices of federal prosecutors. In this role, Marcus worked on the senior management team with responsibility for the Criminal, Civil, Appellate, Asset Forfeiture and Administrative Divisions.

During Marcus' career with Southern Florida's US Attorney's Office, he held several roles including serving as a deputy chief in the Major Crimes Section, where he trained and supervised AUSAs, led the Identify Theft and Economic Crimes Task Force and oversaw financial investigations in the Major Crimes Section. As an AUSA, he prosecuted cases involving money laundering, healthcare fraud, mail fraud, wire fraud, national security issues and other matters.

Prior to joining the US Attorney's Office, Marcus was the chief of staff for US Representative Peter Deutsch of Florida's 20th Congressional District. He joined the congressman after working for TSIC, Inc., a statewide nonprofit organization that provides full-tuition, four-year college scholarships to thousands of Florida's low-income students. At TSIC, Marcus served as chief operating officer and legal counsel and later as president.

Earlier in his career, Marcus was selected by the Attorney General's Honors Program to work as an attorney in Appellate Section of the Tax Division of the United States Department of Justice in Washington. He also clerked for Judge H. Robert Mayer of the United States Court of Appeals for the Federal Circuit in Washington, DC.
