The ICE Accountability Act establishes an independent Commission for Independent Monitoring of Immigration Enforcement within the legislative branch. This Commission is designed to ensure rigorous oversight, transparency, and accountability of immigration agencies, including Immigration and Customs Enforcement (ICE) and U.S. Customs and Border Protection (CBP) , regarding their compliance with constitutional, statutory, and policy requirements. The Commission's duties include monitoring enforcement activities, conducting on-site visits, and reviewing extensive data and records from the Department of Homeland Security. It will issue monthly public reports to Congress, maintain a public website for complaints and data, and review public submissions to inform its findings. A key provision allows the Commission, with a three-fourths vote of its monitors, to issue formal findings of serious violations, refer matters for criminal prosecution, hold public hearings, and recommend reforms to Congress. Furthermore, the Commission possesses significant authorities, including unrestricted access to DHS systems, facilities, and personnel, and the power to issue subpoenas if access is denied. For serious or willful violations, the Commission can initiate civil actions in federal court, potentially leading to judicial orders and substantial daily penalties of $500,000 against non-compliant immigration agencies. The bill also includes strong protections for whistleblowers who report information to the Commission. The Commission will consist of four monitors, appointed by bipartisan congressional leadership, who must have extensive expertise and serve full-time for five-year terms. These monitors and staff are prohibited from holding other government employment and must be free of conflicts of interest. The Commission is authorized to operate until immigration agencies demonstrate sustained substantial compliance, with a mechanism to pause termination if non-compliance resumes.
