WASHINGTON, June 26 (Reuters) - Reality TV star Paris

Hilton is set to testify before a U.S. House of Representatives

committee hearing on Wednesday, in support of reauthorization of

a federal program responsible for children in foster care.

Hilton, 43, the great-granddaughter of Hilton Hotels founder

Conrad Hilton, has spoken publicly about the alleged emotional

and physical abuse she endured when she was placed in

residential youth treatment facilities as a teen.

Hilton first described her experience at a Utah facility -

which she said has left her with post-traumatic stress disorder

that she continues to suffer from - in 2021, and has been a

vocal advocate for greater oversight of the system.

"If I tried to tell my parents about the abuse, the staff

would immediately rip the phone from my hand, disconnect the

call and I'd be subject to violent physical restraints and

solitary confinement," Hilton told a California state

legislature committee in April, part of a push to pass a bill

requiring more transparency from youth treatment facilities.

Hilton, along with several other witnesses, is expected to

testify about how the U.S.' child welfare program can be

improved, including how to improve interventions before foster

care is needed and prioritizing keeping children with family

members.
