A conservative legal group founded by senior White House adviser Stephen Miller is urging Congress to investigate a partnership between Apple and OpenAI, arguing the companies have effectively locked millions of people into a single, politically biased artificial intelligence system.

In a letter sent to Senate Judiciary Committee Chairman Chuck Grassley (R-IA) and House Judiciary Committee Chairman Jim Jordan (R-OH), America First Legal called for a congressional investigation into what it described as a “collusive arrangement” that made ChatGPT the exclusive AI chatbot integrated into iPhones and other Apple products. The group said Apple’s integration of ChatGPT into Siri and other core features effectively denies users meaningful choices for alternatives while steering hundreds of millions of smartphone users toward a single AI platform.
