Federal authorities are pushing back against reports that they neglected 50 immigrant women and children who were dropped off at a bus station Friday and were later stranded in San Antonio due to Hurricane Harvey, saying the immigrants had confirmed tickets and itineraries when they were dropped off.

The asylum seekers, mostly from Central America, were dropped off at the bus station and were due to travel to cities and towns across the U.S. after passing their “credible fear” interviews. However, their plans were waylaid when Hurricane Harvey forced Greyhound Bus to cancel many of its afternoon services, stranding them at the station.
