US lawmakers want to sanction a Nigerian politician using data the BBC proved was invented

Two Republican congressmen introduced the Nigeria Religious Freedom and Accountability Act of 2026 on Tuesday. It targets Rabiu Kwankwaso, who left the Kano governorship in 2019 and holds no current public office, with visa bans and asset freezes. It seeks to designate Miyetti Allah as a foreign terrorist organisation. It calls for annual reports on Christian persecution and asks whether US assistance to Nigeria encourages religious violence.

The bill's foundation is a claim that between 50,000 and 125,000 Christians were killed in Nigeria between 2009 and 2025. BBC investigated that figure last November. The New York Times went further in January. The organisation behind the numbers, run by a man named Emeka Umeagbalasi, couldn't produce a verifiable methodology. When asked for evidence, it gave summaries. When pressed, Umeagbalasi confirmed he hadn't verified the data himself.

That should end the story. It doesn't.

A bill in Congress doesn't need accurate data to reshape how American officials think about Nigeria. It creates a record. It gives language to hearings, briefings, and diplomatic pressure. It influences the environment in which Nigerian visa applications are processed and aid decisions are made. Trump already designated Nigeria a Country of Particular Concern based on similar lobbying. Nigeria spent $4.5 million on a Washington lobbying firm this year to manage this exact kind of reputational exposure.

The bill still has to pass both chambers and be signed by Trump. But the damage a bill can do doesn't begin at enactment. It begins the moment it gets introduced and picked up by officials looking for a framework.
