Photos of crowded migrant holding center in Texas released by Democratic congressman

Photos of migrants in a crowded border facility in Donna, Texas, were released Monday by the office of Rep. Henry Cuellar, D-Texas, as the Biden administration limits media access to the southwestern border. 

The migrants, who are in clear pens akin to cages, are seen sleeping on pads on the floor with aluminum blankets. In some instances, it appears that dozens are sharing individual pens. Most appear to be wearing masks.

Amid a significant surge of migrants to the southern border in President Biden's first two months, some in the media have complained about a lack of access to facilities like the one in Donna. 

"I respectfully ask US Customs and Border Protection to stop blocking media access to their border operations," award-winning photojournalist John Moore tweeted Friday. "I have photographed CBP under Bush, Obama and Trump but now - zero access is granted to media. These long-lens images taken from the Mexican side."

He added: "There’s no modern precedent for a full physical ban on media access to CBP border operations."
