Robby Mook, Hillary Clinton's 2016 campaign manager, and Matt Rhoades, Mitt Romney's 2012 campaign manager, are working together on a bipartisan Defending Digital Democracy (DDD) project, aimed at protecting voting from cyberattack.

The project, launched Tuesday by the Belfer Center for Science and International Affairs at the Harvard Kennedy School, will include experts from the national security and technology communities, including Facebook and Google.

The mission: "identify and recommend strategies, tools, and technology to protect democratic processes and systems from cyber and information attacks ... concrete solutions to an urgent problem."
