A second private Facebook page, in which Customs and Border Patrol agents degraded migrants, minority groups, and lawmaker Alexandria Ocasio-Cortez, has been discovered, two sources familiar with the Facebook page told CNN.

The discovery of the page, called "The Real CBP Nation," followed a ProPublica investigation that revealed the existence of a secret Facebook group that featured sexist and xenophobic posts about migrants who died crossing into the country or while in US custody.

A second private Facebook page connected to Customs and Border Patrol agents that includes degrading comments about migrants and rep. Alexandria Ocasio-Cortez has been discovered, two sources familiar with the Facebook page told CNN.

The Facebook group, called "The Real CBP Nation," has around 1,000 members and includes memes taunting Ocasio-Cortez, an image mocking the separation of migrant families, and derisive images of minority groups.

The discovery of the page comes after the investigative newsroom ProPublica revealed a secret CBP Facebook group, "I'm 10-15," which included around 9,500 members from across the country. The page included sexist and xenophobic posts about migrants who died crossing into the country or while in US custody, and also featured lewd imagery of Alexandria Ocasio-Cortez.

A source told CNN that the group "I'm 10-15" was archived on Monday to prevent additional comments from being posted.

Following the ProPublica investigation, Ocasio-Cortez accused the US Border Patrol of having "a violent culture," questioning "How on earth can CBP's culture be trusted to care for refugees humanely?"

"The Real CBP Nation" Facebook page also mocked the New York lawmaker, according to CNN. For example, a manipulated meme of Ocasio-Cortez shows her gesturing toward a water fountain with the caption "is this a toilet?" Earlier this week, after touring Border Patrol facilities in El Paso and Clint, Texas, Ocasio-Cortez described a woman who was told by an agent to drink out of the toilet.

A CBP spokesperson told Business Insider that they received screenshots of social media posts allegedly by CBP employees and shared those posts with the Office of Professional Responsibility, which investigates potential employee misconduct.

"CBP does not tolerate misconduct on or off duty and will hold those who violate our code of conduct accountable. These posts do not reflect the core values of the agency and do not reflect the vast majority of employees who conduct themselves professionally and honorably every day, on and off duty," the spokesperson said.
