Georgetown Law’s faculty page states that Mary McCord was Acting Assistant Attorney General for National Security at the U.S. Department of Justice from 2016 to 2017, and Principal Deputy Assistant Attorney General for National Security from 2014 to 2016. That is the title lock. It is not a finding that she “led Russiagate.” That phrase is opinion and is not used as fact here.
Fox News, carrying Associated Press, April 20, 2017: a top national-security official would leave the Justice Department. A follow-up AP piece on Fox, April 28, 2017, said Dana Boente was named acting national-security leader. The articles are reporting. They document a departure window. They do not invent a firing for cause.
Her June 9, 2026, House Judiciary witness statement (Congress.gov PDF) dates her earlier career: Assistant U.S. Attorney, U.S. Attorney’s Office for the District of Columbia, 1994–2014, including Deputy Chief, Appellate Division, and Chief, Criminal Division. Faculty: J.D., Georgetown; clerk to Judge Thomas Hogan, U.S. District Court for D.C.
Identity confidence is high when the name is tied to Georgetown, ICAP, and NSD. The personal name is common. This file is Mary B. McCord, the former Acting AAG, not an unrelated local-news namesake.
