In an attack that apparently came from a Russian intelligence agency—and that may or may not be related to similar recent cyber attacks on other Democratic party organizations—computer systems tied to Hillary Clinton’s presidential campaign have been hacked, New York Times and Reuters reported on Friday.

“An analytics data program maintained by the DNC, and used by our campaign and a number of other entities, was accessed as part of the DNC hack. Our campaign computer system has been under review by outside security experts,” Clinton campaign spokesman Nick Merrill said in a statement. “To date, they have found no evidence that our internal systems have been compromised.”

The Department of Justice’s national security division is investigating whether this hack—as well as attacks on servers belonging to the Democratic National Committee and the Democratic Congressional Campaign Committee—threatened the United States’ security, Reuters reports. Apparently, this indicates that the Obama administration believes the cyber attacks are state sponsored.

In a statement, the FBI said that it “is aware of media reporting on cyberintrusions involving multiple political entities, and is working to determine the accuracy, nature and scope of these matters.”

“The cyberthreat environment continues to evolve as cyberactors target all sectors and their data,” the statement continued. “The F.B.I. takes seriously any allegations of intrusions, and we will continue to hold accountable those who pose a threat in cyberspace.”

An earlier version of the Times’ story specified that “email accounts connected to the campaign of Hillary Clinton...were hacked.” All mention of email has been removed from the Times’ report.
