The Biden administration is transporting underage migrants from the border on night flights to a suburban New York airport, according to a report from the New York Post.

The Post spotted two planes land at night at Westchester County Airport—roughly 30 miles from New York City—where migrants got off and boarded buses. According to a Post analysis of flight records, around 2,000 migrants detained in Texas have been flown to the airport on 21 flights since Aug. 8.

Most of the passengers “appeared to be children and teens,” according to the Post, but a few appeared to be men in their 20s. Some of the migrants were dropped off to meet sponsors in New Jersey, and others were bused to a residential facility on Long Island.

The White House told the Post that the flights only transport child and teen migrants.

Border crossings by unaccompanied minors have surged this year since the Biden administration suspended summary expulsions of unaccompanied children. The United States saw encounters with illegal immigrants at the Mexican border reach a 21-year high this summer.

The Washington Free Beacon reported this month that the Department of Homeland Security is weighing plans to fly migrants to Vermont for processing.
