Rep. Alexandria Ocasio-Cortez took to Twitter on Monday night to defend herself — and once again blast the US Customs and Border Protection agency — after an online report accused her of screaming at federal agents “in a threatening manner” during her highly publicized visit to the southern border.

“To these CBP officers saying they felt ‘threatened’ by me – They were literally discussing making a GoFundMe for an officer who attacked my on my tour [sic],” the congresswoman tweeted. “They’re just upset I exposed their inhumane behavior.”

Ocasio-Cortez insisted that she posed no threat to the agents — not verbally or physically.

“They confiscated my phone, and they were all armed,” she said. “I’m 5’4.”

The Democratic lawmaker appeared to be responding to a Washington Examiner report that accused her of acting unruly during a visit to a Border Patrol facility in El Paso, Texas.

“She comes out screaming at our agents, right at the beginning [of the tour],” recalled a source, who claimed to have witnessed the incident — along with 40 other people.

“Crying and screaming and yelling,” the source said. “The agents, they wanted to respond, but they held back because she’s a congressional delegate. But when you have someone yelling at you in a threatening manner … They were like, ‘Hey, you need to kinda step back.’”

Ocasio-Cortez traveled to the southern border with a number of other congressional Democrats on Monday following reports of terrible conditions and repeated sexual assaults at the facilities.

She accused Border Patrol agents earlier in the day — after her visit to the El Paso center — of forcing migrants to drink out of toilets and live under other extreme conditions while the officers sat back and laughed. The New York legislator claimed to have witnessed the alleged abuse firsthand.

“This was them on their GOOD behavior in front of members of Congress,” she said.

CBP officials denied the toilet accusations, insisting that the locations Ocasio-Cortez visited on Monday have standard-issue jail-type appliances with sinks that dispense safe drinking water attached to toilets in a single unit.

“‘No one is drinking toilet water,” an official said. “They’re drinking potable water from the sink attached to the toilet.”

The accusation came just hours after Ocasio-Cortez called out CBP agents for allegedly making threats to her life on social media.

”A secret Facebook group of 9,500 CBP officers discussed making a GoFundMe for officers to harm myself & Rep. Escobar during our visit to CBP facilities & mocked migrant deaths​,” she tweeted. “This isn’t about ​’​a few bad eggs.​’​ This is a violent culture.​”
