The FBI on Monday confirmed it has opened an investigation into claims that the Wikileaks email dump of nearly 20,000 DNC emails over the weekend might be linked to the Russian government. Hackers connected to Russian intelligence agencies allegedly have been working to help tilt the U.S. presidential election. Hillary Clinton's campaign manager, Robby Mook, made a bombshell allegation on Sunday, claiming that the hack of thousands of DNC emails that revealed efforts to undermine the Bernie Sanders campaign was the work of Russian intelligence.
