State attorneys general increasingly are asserting authority in an area once viewed as the exclusive province of federal national security regulators — scrutinizing who can access sensitive personal data of U.S. persons, where that data flows, and whether foreign governments have legal rights or practical means to control or obtain the data. Recent actions by Florida, Texas, and Arizona Attorneys General illustrate a clear and accelerating trend — national security concerns are no longer abstract policy considerations in the data privacy space; they are becoming a basis for hands-on investigative and enforcement activity at the state level, increasingly aligned with parallel developments at the federal level.

In February 2026, two federal courts drew national attention by addressing generative AI in the privilege context. At first glance, the decisions appear incongruent: one denied privilege where AI was used; the other upheld work product protection in a similar context. Yet neither decision announced a shift in privilege law. Each applied existing principles to new factual settings. The practical implications are straightforward: understand the confidentiality terms governing AI platforms, ensure appropriate attorney involvement where privilege is sought, and maintain disciplined policies around AI-assisted legal analysis.

Last week, the House Energy and Commerce Committee voted to send the Right to Equitable and Professional Auto Industry Repair (REPAIR) Act to the full U.S. House of Representatives for consideration. This legislation, if enacted, would give car owners access to their vehicle-generated data and repair data and tools from vehicle manufacturers. It would also grant owners certain rights over the use of that data, including the right to delete it, and would prevent recipients of vehicle-generated data from selling, transferring, or licensing that data absent certain exceptions. As indicated by its name, the REPAIR Act is reflective of the so-called “right to repair” movement to allow consumers and independent repair shops access to the same data for repair and maintenance that manufacturers make available to themselves or franchised dealers. It also has important implications for data privacy in modern vehicles, which generate increasingly large volumes of information.

Recent developments in children’s privacy and online safety regulation reflect a global shift away from notice-and-consent frameworks toward access restrictions, design mandates, categorical advertising prohibitions, and ecosystem-level age-assurance mechanisms. Using Australia’s under-16 social media ban as a case study, this article examines four converging regulatory trends emerging across the United States, Europe, and the United Kingdom. These developments increasingly affect product design, advertising, and data governance decisions for companies operating consumer-facing digital services.

Concerns about the impact of social media on children and adolescents have grown among U.S. lawmakers, parents, and public health officials. While federal oversight remains largely limited to narrow data privacy protections for minors, states have moved to fill the gap with a wave of laws governing minors’ access to and use of social media platforms. Companies should closely track these developments to anticipate new obligations and adapt their policies and procedures on a jurisdiction-by-jurisdiction basis. Read the full article to learn more about emerging state laws, enforcement trends, and practical steps companies can take to prepare.

Blockchain technology and asset tokenization are moving beyond proof-of-concept use cases to production-scale systems, requiring businesses and regulators to confront questions that are no longer theoretical. As institutional adoption expands and rulemaking, enforcement, and litigation accelerate across jurisdictions, the legal consequences of how these technologies are structured, deployed, and governed have become more immediate and more complex.
