SACRAMENTO, Calif. (AP) — Paris Hilton joined California state lawmakers Monday to push for legislation aimed at cracking down on the industry that cares for troubled teens by requiring more transparency from youth treatment facilities.

The bill supported by the Hilton Hotel heiress and media personality aims to pry open information on how short-term residential facilities for youth dealing with substance abuse and behavioral issues use disciplinary methods such as restraints or seclusion against minors. It would require such centers to notify parents and the state any time they use restrains or seclusion rooms for minors. It’s authored by Republican state Sen. Shannon Grove and Democratic state Sens. Aisha Wahab and Angelique Ashby.

“I know firsthand the horrors that happened behind the closed doors of youth residential treatment facilities,” Hilton said at a Monday news conference at the state Capitol. “In troubled teen industry facilities in California, Utah and Montana, I was subjected to abuse disguised as therapy, isolated from the outside world and denied even the most basic rights.”
