State Attorneys General

Open PDF

Wilson Sonsini’s State Attorneys General (SAG) practice is anchored by a core team that represents clients in high-profile matters undertaken by SAG offices, including multi-state and joint state-federal investigations and lawsuits, and other enforcement efforts. As the number of inquiries, regulatory measures, and enforcement campaigns originating from SAG offices has increased in recent years, so too has our work on behalf of clients in such matters. These controversies have encompassed areas ranging from digital applications and ESG issues to fraud allegations and transportation—and our attorneys’ extensive antitrust, privacy, cybersecurity, and consumer protection experience allows them to confidently guide clients through the process of responding to SAG actions.

An Experienced Team

In representing clients confronted by SAG challenges, Wilson Sonsini has drawn from an experienced team of litigation and regulatory attorneys across multiple practice areas and industry groups. Our core SAG practice consists of more than 25 attorneys; however, the number of our firm’s attorneys who have been involved in recent SAG matters or have highly relevant experience is much larger. Our core team includes:

  • a former deputy attorney general in the antitrust section of the California Attorney General’s office;
  • a former antitrust bureau chief at the New York Attorney General’s Office;
  • a former antitrust counsel in the Missouri Attorney General’s Office;
  • a former assistant to the U.S. Solicitor General;
  • a former assistant solicitor general for the State of Alabama;
  • multiple former prosecutors in U.S. Attorney’s Offices across the country, including U.S. Attorneys for the Districts of Utah and Nevada;
  • several former state district attorneys;
  • multiple Wilson Sonsini attorneys who previously held senior enforcement positions in federal regulatory agencies, including the DOJ, FTC, and SEC; and
  • five former federal or state judges.

Our attorneys draw on experience gained through current and past roles to advise and represent clients effectively when investigations are initiated by SAG offices. Clients benefit from our attorneys’ situational awareness, which is sharpened by their familiarity with prosecutorial and enforcement tactics. Further, based on their collective experience, our team can lead investigations of any size and scope, from short-term, fact-finding inquiries to long-term comprehensive probes involving highly sensitive issues.

In addition to our SAG team’s substantial state-level experience and prior positions, our team’s federal-level experience–specifically having former federal regulators, enforcers, and judges who are experienced in addressing complex matters–is important in situations when state and federal agencies are either working together in concurrent state/federal investigations or situations where their respective interests may not be aligned.

Our team includes attorneys from the following practice areas who have represented clients in several industries, including the sectors listed below:

Practice Areas

  • Antitrust
  • Class action litigation
  • Consumer litigation (particularly advertising and marketing practices)
  • Data, privacy, and cybersecurity
  • Energy and climate solutions
  • Environmental, Social, and Governance
  • False claims (state laws)
  • Financial corporate fraud (securities fraud, kickbacks)
  • Internet strategy and litigation
  • Regulatory healthcare
  • White collar criminal defense
   

Industry Groups

  • Artificial Intelligence
  • Blockchain and cryptocurrency
  • Communications
  • Consumer products and services
  • Digital health
  • Fintech and financial services
  • Internet
  • Life sciences
  • Mobility
  • Payments

Strong Relationships Lead to Favorable Results

Through prior roles and matters undertaken since joining Wilson Sonsini, our attorneys have established strong ties to Attorneys General offices in states across the country. It is because of these strong relationships that, in the early stages of a SAG investigation, we have helped clients develop and evaluate available strategies and, in certain cases, significantly narrowed the scope of the investigation or convinced the SAG office(s) involved that charges were not warranted. In some instances, we helped clients achieve complete containment. In others, we secured settlements resulting in limited or no financial penalty or admissions of wrongdoing.

Agri Stats Settlement Clarifies DOJ Views on Information Sharing
On May 7, 2026, the U.S. Department of Justice (DOJ) Antitrust Division and six state attorneys general filed a proposed Final Judgment to resolve antitrust claims against benchmarking and consulting firm Agri Stats, Inc. (Agri Stats). Agri Stats collects, processes, and distributes benchmarking data to broiler chicken, pork, and turkey processing operations. The reports are based on non-public pricing, profitability, and cost data submitted by meat processors. While Agri Stats purported to aggregate and anonymize the data, the DOJ alleged that those receiving the reports could identify who submitted the non-public data, allowing participants to raise prices.

State Coalition Claims Victory in Live Nation Monopolization Trial
On April 15, 2026, a federal jury found Live Nation liable for monopolization. The case was initially filed by the U.S. Department of Justice (DOJ) and joined by 40 attorneys general (AGs) from the states and the District of Columbia, but the DOJ reached a surprise mid-trial settlement limited to behavioral remedies. A broad coalition of 34 of the AG plaintiffs, from both political parties, rejected the federal settlement as inadequate and continued to litigate the case, culminating in a resounding verdict for the states on all counts tried.

Trump Administration Issues Executive Order on National AI Policy and Deregulation
On December 11, 2025, the White House issued an Executive Order (EO), “Ensuring a National Policy Framework for Artificial Intelligence,” that establishes a new federal policy on artificial intelligence (AI). The EO states that it is “the policy of the United States to sustain and enhance the United States’ global AI dominance through a minimally burdensome national policy framework for AI.” The EO asserts that leadership in AI is critical to U.S. national and economic security and dominance and that “AI companies must be free to innovate without cumbersome regulation.” To accomplish this, the EO seeks to challenge “onerous” state AI laws through various federal actions.

California Enacts Major AI Safety Legislation for Frontier AI Developers
On September 29, 2025, California Governor Gavin Newsom signed into law Senate Bill 53, the Transparency in Frontier AI Act (TFAIA), the first-of-its-kind AI legislation in the U.S. that will require large AI developers to publicly disclose how they plan to mitigate potentially “catastrophic risks” posed by advanced frontier AI models. The law builds on recommendations from the June 2025 report from the Joint California AI Policy Working Group and is a pared-back successor to last year’s unsuccessful Senate Bill 1047, which was vetoed amidst industry opposition. Most provisions of SB 53 will be effective starting January 1, 2026.
