SAN FRANCISCO (AP) — A researcher at Texas A&M University flying home from abroad was detained for more than a week by immigration authorities at the San Francisco International Airport, sleeping in a chair and living off food sold in the airport, his family and attorneys said Thursday.

The Trump administration’s immigration crackdown appears to have kept a Texas scientist who was born in Korea locked inside San Francisco International Airport for over a week with little access to basic necessities, according to the man’s attorney.

A doctoral student at Texas A&M who was held by immigration agents at an airport for a week is now detained in Arizona and remains in removal proceedings.
