Young sobbing children without their parents and families sleeping on cement floors with nothing but thin Mylar emergency blankets were the tragic scenes Rep. Barbara Lee (D-Calif.) witnessed in a tour of a Texas intake and detention facility for immigrants.

It was heart-wrenching, she said Sunday on CNN s State of the the Union. The images we see on the media really speak volumes to whats taking place, but when you see it in person, its .. its .. horrific.

Lee was one of some two dozen politicians who toured Texas facilities in McAllen and near Brownsville on Saturday. They were not allowed to take photos of what they witnessed, she said. Lee said she saw a boy and a girl, both about 3 years old, crying alone in separate cells in one of the facilities.

When Lee asked a guard why the children and families had to sleep on cement, he said: We just dont have the resources. I said, Wait a minute, the Defense Department has a lot of resources. Im sure we could find out of that $700 billion dollar budget enough resources to bring cots in or pads for these children.

Its tragic, she said. These people are being criminalized. These are jails. These are prisons. Mothers we talked to had no idea where their babies were, where their children were.
