This bill proposes the establishment of an Office of Global Criminal Justice within the Department of State, aimed at enhancing the United States' efforts to address international atrocities. The Office would serve as a central point for advising the Secretary of State and other federal officials on issues related to war crimes, crimes against humanity, and genocide. Its core duties include formulating U.S. policy on the prevention of, responses to, and accountability for such atrocities. The Office would also coordinate U.S. Government positions on international and hybrid courts, and collaborate with other governments and organizations to establish and support investigative and prosecutorial bodies. Furthermore, it would coordinate the deployment of various tools—diplomatic, legal, economic, and military—to collect evidence, judge perpetrators, protect victims, and promote the rule of law. The Office would also provide expertise on transitional justice mechanisms in conflict zones and act as a primary contact for tribunals addressing atrocities. This new office would be supervised by an Ambassador-at-Large for Global Criminal Justice , requiring presidential nomination and Senate confirmation.
