David McGill Partner

Washington, D.C.

The Legal 500 reports that David has earned a reputation among clients for dispensing “invaluable and practical, business-oriented advice,” and his approach to disputes has been praised as “insightful, uber responsive and fearless.”

Known as an aggressive advocate, David is frequently retained by financial firms to design creative solutions for investigations and disputes involving allegations of market misconduct across an array of financial products, commodities, and other asset classes. He has successfully persuaded the U.S. Commodity Futures Trading Commission (CFTC), U.S. Department of Justice (DOJ), and U.S. Securities and Exchange Commission (SEC) to walk away from threatened charges in numerous contexts, and his recent litigation wins include obtaining the first-ever dismissal of a criminal spoofing scheme charge in a commodities futures case. Alternative asset managers and technology companies often turn to David for advice on regulatory and compliance issues, including in the areas of digital currency and exchange enforcement.

David’s practice also extends to intellectual property disputes and investigations into alleged workplace misconduct. He regularly represents technology, sports, and media companies in matters involving allegations of trade secret misappropriation, licensing disputes, unfair competition, and employee/insider misconduct.
