Children detained at border

Inside an old warehouse in South Texas, hundreds of immigrant children wait in a series of cages created by metal fencing. One cage had 20 children inside. Scattered about are bottles of water, bags of chips and large foil sheets intended to serve as blankets. One teenager told an advocate who visited that she was helping care for a young child she didn't know because the child's aunt was somewhere else in the facility. She said she had to show others in her cell how to change the girl's diaper.
