Rep. Alexandria Ocasio-Cortez repeated her claim that US border camps are forcing migrants to drink “toilet water,” while blasting Republicans for their “manufactured crisis” at the southern border.

The freshman congresswoman testified Friday in front of the House Oversight and Reform Committee, where, against protocol, she insisted on being sworn into the hearing to describe her visit last month to border detention centers.

“When these women tell me they were put into a cell and that sink was not working, and we tested the sink ourselves, and the sink was not working and they were told to drink out of a toilet bowl, I believed them,” she said.

Ocasio-Cortez (D-Bronx-Queens) claimed the policies at the border have turned detention centers into “a tinderbox of hurt people who hurt people.”

“What was worse was that there were American flags all over these facilities, that all these children were being separated under all these flags and women were being called these names under all these flags, we can’t allow this,” Ocasio-Cortez said.

Republican lawmakers at the hearing accused the House Democrats of playing down issues at the border with their “manufactured crisis” remarks — and lambasted Ocasio-Cortez’s past comments comparing the facilities to Nazi concentration camps.

“Our own congressional leaders are vilifying the border agents,” said Rep. Chip Roy (R-Texas). “These are the people holding our front lines.”

But Ocasio-Cortez fired back in her testimony, saying, “This is a manufactured crisis because the cruelty is manufactured. This is a manufactured crisis because there is no need for us to do this.”

The New York representative’s testimony came after she and three other freshman Democratic lawmakers — who call themselves “The Squad” — opposed an emergency border spending bill because they didn’t believe it went far enough to protect migrant children.

The vote led to a public fallout between Ocasio-Cortez and House Speaker Nancy Pelosi, who dismissed the foursome’s clout when they voted against the bill.

“All these people have their public whatever and their Twitter world,” the California Democrat told the New York Times. “But they didn’t have any following. They’re four people and that’s how many votes they got.”

Ocasio-Cortez accused the California Democrat of “singling out” her and her fellow newcomers.

She told the Washington Post that “the persistent singling out … it got to a point where it was just outright disrespectful … the explicit singling out of newly elected women of color.”
