The "Governors’ Right to Inspect Act of 2026" allows governors and designated health officials to conduct health and safety oversight inspections in detention facilities, ensuring adequate conditions for detainees. It addresses concerns about overcrowding, inadequate sanitation, and substandard medical care, following a surge in detention rates and deaths. The bill provides authorized officials the right to access, interview detainees, review records, and document conditions, without interfering in immigration operations. It mandates facility cooperation and security protocols and requires the public release of inspection reports. Additionally, it offers supplemental authority, authorizes appropriations, and will take effect 180 days after enactment.
