The FBI opened a counterintelligence investigation into Lt. General Michael T. Flynn (Ret.) “as part of the larger Crossfire Hurricane umbrella” investigation into the presidential campaign of Donald J. Trump and its possible coordination with Russian officials to interfere with the 2016 presidential election. Code-named “Crossfire Razor,” the investigation’s stated “goal” was to determine whether Mr. Flynn “was directed and controlled by and/or coordinated activities with the Russian Federation in a manner which is a threat to the national security and/or possibly a violation of the Foreign Agents Registration Act, 18 U.S.C. § 951 et seq., or other related statutes.”
