This bill, titled the "AUSSOM Funding Restriction Act of 2025," aims to restrict the use of United States assessed contributions to the United Nations for the African Union Support and Stabilisation Mission in Somalia (AUSSOM) and any other African Union-led peace support mission in Somalia. It specifically targets funding under United Nations Security Council Resolution 2719 (2023), which outlines conditions for UN assessed contributions to African Union peace support operations. The legislation emphasizes a policy of supporting Somali- and African partner-led initiatives while ensuring fair burden sharing and upholding the strict conditions set forth in Resolution 2719.

A core provision of the bill is the prohibition on obligating or expending U.S. assessed contributions to the UN for activities related to Resolution 2719 in support of AUSSOM or similar missions in Somalia. The U.S. Ambassador to the United Nations is directed to use the U.S. voice, vote, and influence to oppose any UN Security Council resolution authorizing such funding. However, exceptions are made for funding the United Nations Support Office in Somalia (UNSOS), voluntary U.S. contributions, humanitarian assistance, and oversight costs.

To ensure accountability and compliance, the bill mandates that the Secretary of State conduct an annual independent assessment of the African Union's ability to meet the terms and conditions of Resolution 2719. These conditions include a funding cap of 75 percent from assessed contributions, compliance with human rights and conduct policies, prioritization of civilian protection, and the existence of appropriate accountability mechanisms. Furthermore, the Secretary of State must submit an annual report to Congress detailing these assessment findings, U.S. contributions, AUSSOM's performance, and the status of alternative funding mechanisms.
