The FBI reportedly did not inform U.S. government officials that a Russian hacking operation was attempting to breach their personal emails.
According to an investigation by The Associated Press, the bureau possessed evidence for a year that showed the officials were targets of a Kremlin-linked hacking entity known as Fancy Bear.
The AP said that in the course of its almost 80 interviews, it identified only two instances in which the bureau informed the officials.
Three sources confirmed to the news outlet that the bureau was aware of the cyber efforts for over a year.
“The FBI routinely notifies individuals and organizations of potential threat information,” the FBI said in a statement to the AP.
