Advocates asked for time before the beginning of a video meeting Saturday morning with several Biden administration officials, including people from the Department of Homeland Security officials and the White House Domestic Policy Council’s Esther Olavarria. The activists read a statement accusing the administration of “playing politics with human lives” and said they could no longer “come into these conversations in good conscience.”

“We have sadly reached a turning point,” they said, then most of the advocates exited the video call.

“I cannot stand one more meeting of them pretending,” said Ariana Saludares, a 40-year old advocate from the New Mexico-based Colores United, who was in the meeting. “They give us accolades on the outside, but on the inside, we’re having to take out the metaphoric knives from our back.”

The meeting and the subsequent walk out was prompted by the administration’s plans to reinstate Migrant Protection Protocols, also known as the “Remain in Mexico” policy.
