Gibson, Dunn & Crutcher LLP

Gibson, Dunn & Crutcher LLP’s National Security practice is recognized for handling some of the most sensitive congressional investigations, sanctions mandates, and export controls matters confronting global companies and financial institutions. Co-led by Zainab Ahmad in New York and David P. Burns in Washington DC, the team draws on deep enforcement experience across the full spectrum of national security risk. Ahmad, a former federal prosecutor, is a trusted adviser on high-profile regulatory and internal investigations, while Burns brings senior DOJ leadership experience spanning sanctions, FARA, export controls, and complex government-facing disputes. The DC team is particularly noted for its strength in congressional oversight and trade enforcement work. Michael D. Bopp leads major investigations before the House and Senate, including representing 23andMe in inquiries concerning genetic data privacy and the national security implications arising from its bankruptcy sale. On the sanctions and export controls side, Christopher Timura and Adam Smith advise clients on evolving Russia-related measures, voluntary disclosures, and multi-jurisdictional compliance programs.
