Arnold & Porter Strengthens State Attorneys General Investigations & Litigation Practice with Dedicated Task Force
NEW YORK and WASHINGTON, D.C., March 2, 2026 — Clients face increasing scrutiny and regulatory risk from state attorneys general (AGs), who have aggressively sought to fill the gap left by diminished federal enforcement. In recognition of the increased investigation and litigation activity by state AGs, Arnold & Porter has formed a dedicated State Attorneys General Investigations & Litigation Task Force, a multidisciplinary team led by former state and federal government prosecutors and enforcers that will advise and defend clients facing increasingly complex, high-stakes investigations and litigation involving state AGs.
“For many years, we have helped clients stay ahead of the curve with strategic, proactive counsel that mitigates risk,” said Benjamin Mizer, former Acting Associate Attorney General at the U.S. Department of Justice. “This Task Force helps us coordinate our deep bench of litigators and regulatory attorneys with first-hand knowledge of some of the nation’s most active state AGs. Having been on both sides of the table, our team understands how state AGs think and what drives their decision-making. This group has the experience, relationships, and insight to help guide clients through these complex challenges and understands the nuances of state-level enforcement.”
“Regulated entities increasingly find themselves facing conflicting enforcement demands, caught between federal and state authorities who take opposing views of compliance obligations,” added Meredith Osborn, former Chief Trial Deputy at the City Attorney’s Office for San Francisco. “Arnold & Porter has guided clients caught in these kinds of dilemmas, and today’s changing enforcement landscape is the perfect time to concentrate that expertise in a targeted State AG Task Force.”
Arnold & Porter has a long history of success in single- and multi-state AG matters, often resolving investigations favorably and discreetly before they escalate, as well as aggressively litigating in state court when necessary. Having forged significant relationships with many state AGs, the group helps clients proactively identify issues, provide guidance to avoid inquiries and litigation, anticipate where investigators may focus their efforts, and devise effective, practical measures to limit our clients’ exposure. The Task Force will also monitor state regulatory and litigation developments to keep clients ahead of emerging enforcement trends nationwide.
Collectively, the team brings decades of experience advising on government investigations and litigation across a broad swath of industries, including the pharmaceutical and healthcare, financial services, energy, consumer products, and many other industries.
