Government Enforcement

KKL represents clients involved in government investigations, including those conducted by federal, state, and international criminal authorities, as well as regulatory agencies.

Our founding partners are veteran federal prosecutors who served for years as senior members and supervisors in the Criminal Division of the U.S. Attorney’s Office for the Southern District of New York (SDNY), and in those capacities conducted and supervised hundreds of complex and sensitive investigations.

We have extensive experience with government investigations and parallel regulatory investigations involving a wide array of issues, including insider trading, accounting fraud, tax fraud, market manipulation, U.S. Foreign Corrupt Practices Act (FCPA) violations, sophisticated financial fraud, money laundering, bribery of public officials, cybercrime, national security, and sanctions violations.


KKL brings to bear our decades-long experience as federal prosecutors to conduct efficient, independent investigations and to represent individuals in that context. We focus our practice on highly-sensitive internal matters, including cross-border matters that involve simultaneous criminal and regulatory investigations. We have conducted independent investigations for committees of corporate boards and represented individuals, including corporate officers and board members, in such investigations.

Complex Commercial Litigation

KKL provides effective and efficient advocacy in a broad range of complex commercial litigation in federal and state court proceedings. We seek innovative fee structures that align with our goal of providing streamlined counsel rigorously focused on achieving our client’s objectives.


KKL guides companies through cyber-related and data privacy issues that arise before, during, and after a breach or other cybersecurity incident. We have supervised many of the Department of Justice’s investigations into the most sophisticated computer intrusions and data breaches. This knowledge and experience helps KKL to identify and address the critical vulnerabilities and advanced adversaries our clients face.
