"Between mid-January 2017 and early February 2017, three congressional committees... announced that they would conduct inquiries, or had... been conducting inquiries, into Russian interference... Then-FBI Director James Comey later confirmed... the existence of the FBI's investigation into Russian interference that had begun before the election. On March 20, 2017, in open-session testimony before HPSCI, Comey stated: I have been authorized by the Department of Justice to confirm that the FBI, as part of our mission, is investigating the Russian government's efforts to interfere in the 2016 presidential election, and that includes investigating the nature of any links between individuals associated with the Trump campaign and the Russian government and whether there was any coordination between the campaign and Russia' s efforts .... As with any counterintelligence investigation, this will also include an assessment of whether any crimes were committed.The investigation continued under... Comey for the next seven weeks until May 9, 2017, when... Trump fired Corney as FBI Director—an action which is analyzed in Volume II of the report."
