Senator Okiya Omtatah has filed a lawsuit to halt the implementation of a Ksh. 208 billion health agreement between Kenya and the United States, signed on December 4, 2025. He argues that the agreement, which would see the U.S. invest directly in Kenya's health institutions over five years, was signed without public participation or parliamentary approval, violating constitutional provisions.

• The agreement involves an investment of USD 2.5 billion (Ksh. 208 billion) from the U.S. government into Kenya's health institutions over the next five years.
• Senator Omtatah claims the framework bypasses key legal processes and risks mismanagement of funds, citing the lack of safeguards for direct funding and the burden of Kenya's commitment to match U.S. funding (estimated at USD 850 million).
• He contends that the agreement's ratification as a treaty requires negotiation by the Executive and parliamentary approval, which was overlooked in a "rushed" signing process.
