DLA Piper LLP (US)

DLA Piper LLP (US)’s National Security and Global Trade practice is noted for its strength in navigating the increasingly complex intersection of foreign investment regulation, trade compliance, and government-facing enforcement matters. With deep experience across CFIUS, economic sanctions, export controls, tariffs, supply chain risk management, and congressional investigations, the team advises a diverse range of clients on the full spectrum of national security issues shaping today’s global transactional and regulatory environment. The Washington DC-based group is led by global CFIUS co-chair Nicholas Klein, a go-to adviser on the most complex foreign investment reviews, particularly in aerospace, defense, semiconductors, and emerging technology. Christine Daya brings broad expertise across CFIUS, OFAC sanctions, CBP enforcement, and politically sensitive congressional oversight matters, while veteran sanctions specialist Ignacio Sanchez is noted for resolving landmark enforcement and licensing mandates. Former Commerce Chief of Staff and Acting General Counsel Michael Walsh further strengthens the practice’s advanced technology and export controls capabilities. Recent highlights include securing CFIUS approval for South Korea’s LIG Nex1 acquisition of Ghost Robotics, advising QIC on its $1 billion investment in PSI Quantum, and serving as lead trade compliance counsel to General Electric on its ongoing three-way corporate separation.
