This legislation, titled the "Protecting Our Children in an AI World Act of 2025," seeks to strengthen federal law against child pornography, specifically targeting content generated using artificial intelligence. It achieves this by amending title 18 of the United States Code in two primary ways. The bill eliminates an affirmative defense in child pornography prosecutions, particularly for cases involving computer-generated images, thereby removing the argument that no actual minor was involved. Furthermore, it expands the definition of "sexually explicit conduct" to explicitly include "simulated obscene exhibition" of various body parts, ensuring that AI-generated content falls under the purview of existing prohibitions. These changes are designed to close legal loopholes and enhance the prosecution of those who create or possess AI-generated child pornography.
