A bill backed by celebrity and entrepreneur Paris Hilton is heading to President Biden's desk after the House passed the act on Wednesday, a week after it was cleared unanimously by the Senate.

The "Stop Institutional Child Abuse Act" requires more oversight for youth residential treatment facilities, a regulation Hilton has spent years lobbying for after testifying that she was sexually abused as a 17-year-old at a Utah boarding school.

The bipartisan bill was co-sponsored by 23 lawmakers including Sen. John Cornyn, R-Texas, Sen. Tommy Tuberville, R-Ala., Sen. Chris Murphy, D-Ct., Sen. Jeff Merkley, D-Ore. and Rep. Ro Khanna, D-Calif.

Once the bill is enacted, the Secretary of Health and Human Services has 45 days to enter into a contract with the National Academics of Sciences, Engineering and Medicine to "conduct a study to examine the state of youth in youth residential programs and make recommendations," according to the text.

Hilton celebrated Congress passing the bill in a social media post on Wednesday where she stated, in part, "today is a day [she] will never forget."

"This moment is proof that our voices matter, that speaking out can spark change, and that no child should ever endure the horrors of abuse in silence. I did this for the younger version of myself and the youth who were senselessly taken from us by the Troubled Teen Industry," she wrote on X.

She thanked the "countless survivors who shared their stories," the "families who stood with us" and the legislators "who chose courage over complacency."

"And to the children still trapped in these systems: I will never stop fighting for you. Change is possible!" she concluded.

The act requires the National Academies to submit a report within three years, and every two years thereafter for a decade, detailing various issues, including the "nature, prevalence, severity, and scope of child abuse, neglect, and deaths" in the programs.

The reports must also include who is funding the youth residential programs at the state and federal levels.

Recommendations will also be made on how to better train those working in fields that may come into contact with institutionalized youth, and how to implement "positive behavioral interventions."

Hilton has also influenced similar legislation protecting institutionalized minors in eight states.

FIRST ON FOX: Sen. Roger Marshall, R-Kan., a former medical doctor, is expected to introduce legislation that would ban gender-related medical procedures on minors and impose a penalty for professionals who perform such treatments, Fox News Digital has learned.

The bill, titled the Safeguarding the Overall Protection (STOP) of Minors Act, aims to prohibit youth gender transition treatment and "castration procedures" by banning "the use of interstate commerce to perform, attempt to perform, conspire to perform, or provide referral for any gender mutilation procedures on a minor."

"Americans resoundingly rejected the Left’s dangerous transgender agenda. Let’s call it exactly what it is: child abuse," said Marshall. 

Marshall is expected to introduce the bill on Capitol Hill on Wednesday: "The days of demented doctors and activists getting rich off of mutilating, sterilizing, and castrating children are over."

The STOP Act, if passed, would call on Health and Human Services (HHS) to impose a civil penalty of at least $100,000 on those "providing transgender mutilation services and treatments" for minors. Secretary Xavier Becerra currently heads HHS under President Biden. However, he will soon be succeeded by Robert F. Kennedy Jr. when President-elect Donald Trump takes office in January. 

GOP LAWMAKERS REVEAL A HEIGHTENED LEGISLATIVE FOCUS AGAINST ‘IRREVERSIBLE’ GENDER SURGERY ON MINORS

The Republican senator's bill also seeks to provide assistance to people who no longer want to continue the gender transition process, commonly referred to as detransitioners.

COURT UPHOLDS RED STATE'S BAN ON TRANS SURGERIES, TREATMENTS FOR MINORS

Marshall signaled he would work with Trump, who has suggested he would seek to slash "gender-affirming" care for minors, on the issue.

"Our legislation keeps children's safety paramount by prohibiting anyone from performing, facilitating, or even conspiring to give these irreversible therapies and procedures to minors," Marshall said. "This bill is just the beginning of what's to come with President Trump at the helm and our unwavering commitment to protecting children from transgender activists' twisted and criminal agenda."

Marshall first teed up the bill during a panel led by Terry Schilling, president of the American Principles Project, and a group of lawmakers who discussed a heightened GOP focus on legislation against transgender medical procedures on minors. 

Lawmakers on the other side of the issue have spoken out in support of such procedures for minors, such as hormone replacement therapy and laser hair removal. Most recently, they pushed back on a ban in Tennessee that prevents minors from receiving puberty blockers.

In September, a total of 164 lawmakers, including 11 senators and 153 representatives in the House, filed an amicus brief defending transgender youth against the ban. 

The Supreme Court will hear arguments regarding the law Wednesday and decide on whether to uphold the ban.
