WASHINGTON (AP) — The Biden administration is seeking the Supreme Court’s go-ahead to end a controversial Trump-era immigration program that forces some people seeking asylum in the U.S. to wait in Mexico for their hearings. The justices are hearing arguments Tuesday in the administration’s appeal of lower-court rulings that require immigration officials to reinstate the “Remain in Mexico” policy. Republican-led states that sued to keep the program in place say it has helped reduce the flow of people into the U.S. President Donald Trump launched Migrant Protection Protocols, as it is formally known, in 2019. President Joe Biden suspended it on his first day in office.
