National Security and Crisis

Organizations operating around the world rely on Jenner & Block’s National Security and Crisis practice to guide them through the complex and ever-evolving landscape of national security-related threats, laws, and policy. From high-profile, precedent-setting litigation involving state-sponsored terrorism or cyberattacks, state secrets, and political suppression, to sanctions, export controls, foreign investment reviews and national security agreements overseen by the Committee on Foreign Investment in the United States (CFIUS), and more, our lawyers bring a global perspective and unmatched experience.

Our team includes high-ranking lawyers and officials within the White House, National Security Council, the Central Intelligence Agency, and the US Departments of Justice, State, and the Treasury. Our unique experience within the government, national security apparatus, and the Intelligence Community allows us to adeptly steer clients through legal and policy challenges as they tackle complex national security-related litigation, compliance challenges, or engage with government entities.

Leading Litigators in Consequential National Security Matters

We regularly represent victims of terrorism, political suppression, and state-sponsored hacking, working to win justice and significant monetary compensation for our clients. Our high impact litigation team has held nation states and significant global political and financial institutions to account, including in multi-billion-dollar proceedings on behalf of 9/11 families against Iran and the Taliban. Our prior government experience and our deep relationships within the National Security Council, Department of State, Department of Commerce, Department of the Treasury, Department of Defense, National Security Agency, Central Intelligence Agency, and Office of the Director of National Intelligence, among others, also gives us a unique ability to advise and defend individuals and corporations facing criminal investigations where national security issues are at play.

A Collaborative Approach to investigations

We help organizations and individuals navigate internal, congressional, civil, and criminal investigations involving sensitive national security issues and classified information. Together with our nationally recognized Investigations, Compliance, and Defense, and Data Privacy and Cybersecurity practices, we help manage risk in the wake of a cyber attack, and when classified or export-controlled information, intellectual property, or other sensitive corporate or national security information has been leaked by an insider, diverted to sanctioned parties, or stolen by malign actors. We also investigate and advise companies and individuals on counterintelligence matters, export and sanctions enforcement, the Foreign Corrupt Practices Act (FCPA), the Foreign Agents Registration Act (FARA), and extradition and INTERPOL notices, among other things.

Transactions Due Diligence to Reduce Compliance Risks

We also advise clients and conduct due diligence to reduce compliance risk in corporate transactions, including on economic sanctions, export controls, and foreign investment in the United States and the United Kingdom. We collaborate closely with other practice groups across the firm when a cross-disciplinary approach is needed to meet our clients’ goals.

National Security Crisis Management Counsel

When a crisis arises, we are here to help. We help clients navigate the intersecting challenges arising from nation-state cyber attacks, media scrutiny, and national security investigations brought by Congressional Committees, Offices of Inspector General, the Department of the Treasury, the State Department, the Commerce Department, the Department of Justice, and the UK government under the National Security and Investment Act, as well as myriad media organizations.

Navigating Sanctions and Export Controls

We work with global businesses to promote and enhance sanctions and export control compliance. We proactively monitor significant developments affecting clients’ global operations to help reduce risk. Should compliance concerns arise, we are there at every step to investigate potential violations and guide clients through voluntary self-disclosures, engage with authorities regarding sanctions or export controls, and conduct compliance reviews and risk assessments to put our clients on a better path forward. In addition to our US expertise, Rob Dalling, our sanctions and export control partner in the London office, provides counselling on these issues to the extent that United Kingdom and European Union issues are implicated.
