How a dubious Russian document influenced the FBI’s handling of the Clinton probe

A secret document that officials say played a key role in then-FBI Director James B. Comey’s handling of the Hillary Clinton email investigation has long been viewed within the FBI as unreliable and possibly a fake, according to people familiar with its contents.

In the midst of the 2016 presidential primary season, the FBI received what was described as a Russian intelligence document claiming a tacit understanding between the Clinton campaign and the Justice Department over the inquiry into whether she intentionally revealed classified information through her use of a private email server.

The Russian document cited a supposed email describing how then-Attorney General Loretta E. Lynch had privately assured someone in the Clinton campaign that the email investigation would not push too deeply into the matter.

.. In the supposed email, Wasserman Schultz claimed Lynch had been in private communication with a senior Clinton campaign staffer named Amanda Renteria during the campaign. The document indicated Lynch had told Renteria that she would not let the FBI investigation into Clinton go too far, according to people familiar with it.

Current and former officials have argued that the secret document gave Comey good reason to take the extraordinary step over the summer of announcing the findings of the Clinton investigation himself without Justice Department involvement.
