A Texas Democrat from the border town of Laredo beat up the Biden government Monday for not being efficient with overcrowded, overcrowded migrant processing plants in the United States

“You’re not moving fast enough, with all due respect,” said Rep. Henry Cuellar. “You should get these kids to Health and Human Services ASAP.”

Cuellar posted photos taken at a border detention facility in Donna, Texas, to highlight the wave of unaccompanied migrant children who have entered the United States in the two months since Biden took office. The pictures show hundreds of young migrants packed in tents, sleeping on mats with thin foil blankets and watching small televisions in the corners.

Nearly 16,000 migrant children were in U.S. custody on Sunday, and more than 800 unaccompanied migrant children had been in border patrol custody for more than 10 days, far longer than the legal limit of 72 hours, according to reports from NBC News.

Cuellar told CNBC’s The News with Shepard Smith that the Biden administration “must work with Mexico and Central America … to make sure those countries help us.” The White House did not immediately return the request for comment.

President Biden has appointed two members of the National Security Council, Roberta Jacobson and Juan Gonzalez, to address the growing influx of migrants at the border. Jacobson and Gonzalez will meet with representatives from Mexico and Guatemala.

Cuellar told host Shepard Smith that the meetings were a promising move, but “they should have done that a long time ago”.

Alejandro Mayorkas, head of the Homeland Security Department, defended the White House’s handling of the border situation on Sunday, saying the border was closed. He did not give a schedule of when new facilities would be opened to help with overcrowding.
