 Paris Hilton is on the Hill today advocating for child welfare. The 43-year-old socialite is testifying before the House in a hearing examining how to strengthen oversight of the facilities. She said she's here to be the voice for the children whose voices can't be heard. Hilton has spoken publicly about being emotionally and physically abused as a teen in residential youth treatment facilities. She said the industry sees kids as dollar signs and operates without meaningful oversight. New York City public schools could soon prohibit students from having cell phones during the day.
