Hillary Clinton's campaign computer networks were also hacked in cyber attacks on Democrats, according to Reuters.
Coming in the wake of the Democratic National Committee and the Democratic Congressional Campaign Committee both being hacked, suspicions have risen that the Russian government may be behind the cyber attacks in order to help Donald Trump's campaign. The Department of Justice is investigating.
The involvement of the Justice Department’s national security division is a sign that the Obama administration has concluded that the hacking was state sponsored, individuals with knowledge of the investigation said.
What content may have been hacked is unknown so far.
The Clinton campaign and the Department of Justice had no comment as to the latest claim.
Clinton's campaign and the Democratic Party has had to deal with fallout from the hacking of the national party's computers. Many of the emails published by Wikileaks showed senior Democratic Party personnel conspiring against Sen. Bernie Sanders (I., Vt.) during the primary. As a result, the chairwoman of the DNC, Rep. Debbie Wasserman Schultz (D., Fla.) was forced to resign.
Criticism has also been directed toward Trump for saying that he hopes the Russians do find more emails of Clinton's and that Trump has made the Republican Party more friendly towards Russia.
