United States v. Flynn was a criminal case in the United States District Court for the District of Columbia. Michael Flynn, a retired Lieutenant General in the United States Armed Forces, had accepted President-elect Donald Trump's offer for the position of National Security Advisor in 2016 and then briefly served as National Security Advisor. He pleaded guilty to one count of making false statements to the Federal Bureau of Investigation. Flynn's alleged false statements involve conversations he had with Russian Ambassador Sergey Kislyak when Flynn was incoming National Security Advisor to President-elect Trump, and Flynn agreed to cooperate with the Special Counsel investigation as part of a plea deal.
