WASHINGTON - Sen. Orrin Hatch is seeking to expand existing protections meant to keep children from being used in pornographic images or movies. Federal law already prohibits using children in production of sexually explicit material, and producers of material depicting sex acts are required to maintain records verifying the age of their performers. Hatch's bill, introduced late Friday, expands those record-keeping requirements, requiring the same record-keeping of those producing materials with simulated, rather than just actual, sex acts. It also expands the definition of sexually explicit material to match the definition in other parts of the law; makes it a crime not to produce those records for inspection; and defines what it means to "produce" sexually explicit material to include distributing the material or managing the content online. It exempts Web-hosting services. -Robert Gehrke
