The matter of the Weiner laptop emails has been debated publicly for more than a year, in part because many Clinton supporters say the FBI tilted the 2016 race toward Donald Trump when it announced in late October that it was reopening its probe into Clinton’s use of a private email server when she served as secretary of state.
Key parts of what went into that decision have remained murky and are a major focus of the inspector general’s probe, according to people familiar with the matter.
In late September 2016, FBI agents in New York were investigating Weiner for possible Internet crimes involving a teenage girl. In the course of that probe, they discovered that his laptop contained thousands of work emails belonging to Weiner’s then-wife, Huma Abedin. Abedin was a longtime aide to Clinton, and agents wanted to know whether the emails in question might shed new light on the Clinton investigation, which had been closed in July without any charges.
The New York FBI office alerted FBI headquarters to the new email issue within days — accounts differ as to when precisely, but McCabe was aware of the matter by late September or early October at the latest, according to the people familiar with the matter. The agents on the Weiner case wanted to talk to the Clinton email investigators and see whether the messages were potentially important. Some people familiar with the matter said officials at FBI headquarters asked the New York agents to analyze the emails’ metadata — the sender, recipient and times of the messages — to see whether they seemed relevant to the closed probe.
McCabe was involved in those discussions, but there are differing accounts about how much then-FBI Director James B. Comey understood about the matter in the early days of October.
An attorney for Comey could not immediately be reached for comment.
So, I think we know why Comey “reopened” the Clinton investigation just days before the election — self-preservation.
