Relatives of Kate Gosselin are expected to testify at a Pennsylvania legislative hearing on child labor laws.
Republican state Rep. Thomas Murt wants to prevent exploitation of children who appear in movies and reality shows like "Jon & Kate Plus 8."
The once-popular TLC show documented the lives of Gosselin, her husband and their eight children at home in Wernersville, Pa. It ended last year after the couple split.
State labor officials investigated the production for possible violations of child labor laws but released no findings. TLC denied wrongdoing.
