America’s digital infrastructure “is literally under attack,” Director of National Intelligence Dan Coats said Friday, with Russia as the most aggressive foreign actor, intent on undermining U.S. democracy.

His remarks came shortly after the Department of Justice announced charges against 12 Russian intelligence officials over alleged efforts to hack into the DCCC, the DNC, and Hillary Clinton’s presidential campaign. The intelligence officials are accused of disseminating the stolen information using the names DCLeaks and Guccifer 2.0.
