Kellen Dwyer is co-leader of the National Security & Digital Crimes Team and a partner in the Litigation & Trial Practice Group. He has litigated cases and defended government investigations involving the Computer Fraud and Abuse Act, the Electronic Communications Privacy Act, the Foreign Agents Registration Act (FARA), and various wiretapping, trade secrets, and national security statutes.
Kellen was previously an assistant U.S. attorney in the Eastern District of Virginia, where he led some of the Department of Justice’s (DOJ) most challenging prosecutions and never lost a case. He obtained a hacking indictment against Julian Assange and represented the United States at Assange’s extradition hearings. Kellen also received the Attorney General’s Award for leading the trial and arguing the appeal in a case involving one of the largest data breaches in U.S. history. He won convictions in dozens of hacking, wiretapping, conspiracy, national security, intellectual property, wire fraud, and public corruption cases.
Kellen was later promoted to deputy assistant attorney general in the DOJ’s National Security Division, where he oversaw the appellate unit, which litigated before appeals courts and advised on sensitive prosecutions, and the legal policy unit, which crafted the department’s positions on cybersecurity, FARA, sanctions, and electronic surveillance matters.
Kellen was a law clerk to Hon. Kenneth Karas on the Southern District of New York and Hon. Diarmuid O’Scannlain on the Ninth Circuit.
