LOS ANGELES (AP) — Three Muslim Americans have filed a lawsuit alleging that U.S. border officers questioned them about their religious beliefs in violation of their constitutional rights when they returned from international travel.

Three men from Minnesota, Texas and Arizona sued Department of Homeland Security officials Thursday in federal court in Los Angeles.

The suit says the questioning violates the men’s rights to freedom of religion and protection against unequal treatment.

A Texas man says he was asked about his religious beliefs and practices at Los Angeles International Airport in 2019 and his personal journal and phone were searched.

A message seeking comment was sent to the Department of Homeland Security.
