Margaret joined Koskoff in 2024, bringing extensive experience as an Assistant United States Attorney in Connecticut and a lawyer in the U.S. Army JAG Corps. Her even-keeled approach to complex legal issues underscores her dedication to accountability and justice. Joining Koskoff to enhance the firearms litigation practice, she began representing government officials in federal litigation in 2025. As a federal prosecutor, her cases involved firearms, domestic terrorism, and violent crimes, successfully trying numerous cases and arguing before the Second Circuit Court of Appeals. Her military career included deployments with the 101st Airborne Division and 5th Special Forces Group, earning a Bronze Star for her service. Margaret teaches courses on federal prosecution and the Russo-Ukrainian War at Yale Law School and is a coordinating attorney with Yale’s Peter Gruber Rule of Law Clinic. Sought after by media like CNN and The New York Times, she frequently provides insights on rule of law and federal criminal justice.
