Ana Suda said she and her friend, Mimi Hernandez, were making a midnight run to the store to pick up eggs and milk. Both are Mexican American and speak fluent Spanish, and they had exchanged some words in Spanish while waiting in line to pay when a uniformed Border Patrol agent interrupted them, Suda said.

“We were just talking, and then I was going to pay,” Suda told The Washington Post. “I looked up [and saw the agent], and then after that, he just requested my ID. I looked at him like, ‘Are you serious?’ He’s like, ‘Yeah, very serious.’ ”

Suda said she felt uncomfortable and began recording the encounter with her cellphone after they had moved into the parking lot. In the video Suda recorded, she asks the agent why he is detaining them, and he says it is specifically because he heard them speaking Spanish.
