WASHINGTON — The federal prosecutor scrutinizing the Russia investigation has begun examining the role of the former C.I.A. director John O. Brennan in how the intelligence community assessed Russia’s 2016 election interference, according to three people briefed on the inquiry.
John H. Durham, the United States attorney leading the investigation, has requested Mr. Brennan’s emails, call logs and other documents from the C.I.A., according to a person briefed on his inquiry. He wants to learn what Mr. Brennan told other officials, including the former F.B.I. director James B. Comey, about his and the C.I.A.’s views of a notorious dossier of assertions about Russia and Trump associates.
