Rep. Alexandria Ocasio-Cortez (D-N.Y.) said that migrant women at a Customs and Border Protection facility in Texas were held in cells without water and told by officers to drink out of the toilet.

“This was them on their GOOD behavior in front of members of Congress,” Ocasio-Cortez tweeted Monday, after her visit to a CBP detention facility in El Paso, Texas. She was part of a delegation of more than a dozen Democratic members of Congress visiting facilities where migrants are held at the border.

“What we saw was appalling and disgusting,” Rep. Judy Chu (D-Calif.) said in a video on Twitter after the visit to the El Paso border patrol station. She echoed Ocasio-Cortez’s account that women detainees said they didn’t have running water, and one said an agent told her to drink from a toilet if she wanted water.

Ocasio-Cortez said she “forced” herself into a cell with migrant women, where one told her officers were waging “psychological warfare” against them by waking them at odd hours and calling them “whores.”

When officers allegedly laughed during the visit in response to migrants drinking out of toilets, Ocasio-Cortez said that a superior she had brought this up to said the officers were “under stress” and acting out.

A CBP spokesperson told HuffPost in a statement Tuesday that migrants at the El Paso and Clint detention centers that lawmakers visited “receive three meals a day and have access to clean drinking water.” The agency noted that officials in El Paso “emphasized” to lawmakers that the facilities were “not designed for long-term holding.”

Visiting lawmakers were not allowed to take pictures or record video at the facilities.

As part of their Texas border visit Monday, House Democrats ― including Reps. Rashida Tlaib (D-Mich.) and Ayanna Pressley (D-Mass.) ― met with activists and advocates, went to an Office of Refugee Resettlement facility holding unaccompanied migrant children, and then visited a detention center in El Paso, before continuing on to another one in Clint.

“This has been horrifying so far. It is hard to understate the enormity of the problem,” Ocasio-Cortez wrote after visiting the El Paso facility. “We’re talking systemic cruelty [with] a dehumanizing culture that treats them like animals.”
