SAN FRANCISCO - The US Federal Bureau of Investigation is pursuing at least three separate probes relating to alleged Russian hacking of the US presidential elections, according to five current and former government officials with direct knowledge of the situation.
While the fact that the FBI is investigating had been reported previously by the New York Times and other media, these officials shed new light on both the precise number of inquires and their focus.
The FBI's Pittsburgh field office, which runs many cyber security investigations, is trying to identify the people behind breaches of the Democratic National Committee's computer systems, the officials said. Those breaches, in 2015 and the first half of 2016, exposed the internal communications of party officials as the Democratic nominating convention got underway and helped undermine support for Hillary Clinton.
The Pittsburgh case has progressed furthest, but Justice Department officials in Washington believe there is not enough clear evidence yet for an indictment, two of the sources said.
Meanwhile the bureau’s San Francisco office is trying to identify the people who called themselves “Guccifer 2” and posted emails stolen from Clinton campaign manager John Podesta’s account, the sources said. Those emails contained details about fundraising by the Clinton Foundation and other topics.
Beyond the two FBI field offices, FBI counterintelligence agents based in Washington are pursuing leads from informants and foreign communications intercepts, two of the people said.
