A federal grand jury has returned an indictment against cybersecurity attorney Michael Sussmann, who represented the Democratic National Committee in connection with the 2016 Russia hack, accusing him of lying to the FBI about who he was representing.

The grand jury indictment accuses Sussmann of lying when he “stated to the General Counsel of the FBI that he was not acting on behalf of any client in conveying particular allegations concerning a Presidential candidate, when in truth, and in fact, as the defendant well knew, he was acting on behalf of specific clients, namely, Tech Executive-1 and the Clinton Campaign.”
