ProPublica published the audio Monday, in which workers are heard attempting to gather information from children in Spanish as they cry out for family members. Through tears, the children repeatedly ask for their “mami” and “papa.”

“Well we have an orchestra here, right? What we’re missing is a conductor,” one border patrol agent is heard joking through the children's cries.

The audio quickly went viral, and was played by reporters in the White House briefing room waiting for press secretary Sarah Huckabee Sanders to arrive on Monday afternoon.

"This entire crisis, just to be clear, is not new," Nielsen said. “Currently, it is the exclusive product of loopholes in our federal immigration laws that prevent illegal immigrant minors and family members from being detained and removed to their home countries."



“Congress and the courts created this system, and Congress alone can fix it,” she added.
