The Stop TNR Act of 2026 addresses transnational repression by creating new criminal penalties and oversight mechanisms for foreign governments that target people in the United States. The bill adds a sentsnational repression law, allowing judges to impose up to 10 additional years of imprisonment and fines up to $100,000 when a federal crime is committed as part of transnational repression activities. The law defines transnational repression broadly to include harassment, threats, surveillance, and violence directed at U.S. citizens or anyone physically present in the country by foreign powers, their agents, or proxies, including tactics that use artificial intelligence, spyware, and cyberattacks. The bill centralizes oversight of these prosecutions within the Department of Justice's National Security Division and requires the Sentencing Commission to update federal guidelines within nine months. Additionally, it mandates annual reports to Congress on transnational repression incidents, briefings on specific cases, development of a government-wide strategy to counter AI-enabled repression, and a review of available sanctions and other tools to deter such conduct.
