This 2018 portrait released by the U.S. Department of Justice shows Connecticut's U.S. Attorney John Durham, the prosecutor leading the investigation into the origins of the Russia probe. Mr. Durham has obtained the complete FBI investigative file on the bureau’s conclusion that there was no secret internet communication channel in 2016 between then-candidate Donald Trump and Alfa Bank, a large Russian lender controlled by Kremlin-tied billionaire oligarchs.
