Algorithmic filtering of American-made products is the subject of a new request for a federal investigation into Amazon and Walmart. U.S. senators urged the Federal Trade Commission to probe whether AI chatbots on the two platforms hide items with "Made in USA" labels from shoppers.

The dispute stems from "label snags" where automated assistants fail to correctly display or prioritize domestic goods. The lawmakers' request targets the integration of artificial intelligence into the merchandising interfaces of the largest e-commerce retailers.
