Migrants held at a border patrol station in Texas were being kept in "horrifying" conditions that included psychological abuse and being told to drink out of toilets, Rep. Alexandria Ocasio-Cortez said after a visit to the facility with other U.S. lawmakers on Monday.

A delegation of lawmakers from the Congressional Hispanic Caucus were touring the border patrol facilities following reports from a government watchdog that immigrants were being housed in overcrowded and unsanitary conditions.

First-term Democratic Congresswoman Ocasio-Cortez wrote on Twitter after leaving the main border patrol station in El Paso that she had seen women in cells with no water who had been told to drink out of toilets.
