FBI Director James B. Comey advised against the Obama administration publicly accusing Russia of hacking political organizations on the grounds that it would make the administration appear unduly partisan too close to the Nov. 8 election, according to officials familiar with the deliberations.
But he supported the administration’s formal denunciation last month as long as it did not have the FBI’s name on it, they said. Comey was sensitive not only to his agency appearing to influence the election but also to seeming biased while it was conducting an investigation into Russian meddling in the 2016 election, said the officials, who spoke on the condition of anonymity to describe internal discussions.
At the same time, the bureau works with Russian services on a variety of terrorism and criminal matters.
