Brown Rudnick launched a National Security practice and expanded its Washington, D.C. presence with a seven-person team that brings experience across U.S. defense, intelligence, security, and government agencies.
The group is led by Patrick Gilman and includes partner Joshua Johnson, counsel Eric Widmar, Director of Intelligence Glenn Corn, and three associates.
The team has experience involving the Department of War, U.S. Intelligence Community, Department of State, Department of the Treasury, Department of Justice, and foreign governments.
Its work will span geopolitical risk, crisis management, incident response, emerging markets, investigations, and remediation and mitigation strategies.
The practice will advise corporations, government contractors, individuals, and government entities on matters where national security intersects with business, policy, regulation, and litigation.
The group will also advise on issues involving the Office of Foreign Assets Control, International Traffic in Arms Regulations, Export Administration Regulations, Foreign Corrupt Practices Act, Committee on Foreign Investment in the United States, Defense Counterintelligence and Security Agency, anti-money laundering rules, and International Humanitarian Law investigations.
Gilman is returning to Brown Rudnick after previously serving as a partner in the firm’s White Collar Defense, Investigations & Compliance practice.
He later led national security practices at two global law firms.
Gilman is a retired Army Judge Advocate and decorated combat veteran who previously served as a national security prosecutor and legal advisor to special operations units.
Johnson previously served as Deputy General Counsel at U.S. Cyber Command and advised the Commander of U.S. Cyber Command and Director of the National Security Agency.
He also served as Senior Counsel for the Cyber National Mission Force’s AI Task Force and Public-Private Collaboration Center.
Widmar is a retired U.S. Army Brigadier General who served as Legal Counsel to the Chairman of the Joint Chiefs of Staff and as Staff Judge Advocate for U.S. Central Command.
Corn spent 36 years in the U.S. intelligence and foreign affairs communities, including senior leadership positions at the CIA and tours as Chief of Station in four Eurasian and Middle Eastern countries.
The launch follows Brown Rudnick’s August 2026 addition of a 34-lawyer intellectual property litigation group and opening of a Silicon Valley office.
