To protest against the Trump Administration’s “zero tolerance” policy on migrants at America's southern border, about 70 children gathered on the floor of Capitol Hill on Thursday, wrapping in Mylar blankets that are similar to the one migrant children have been using in the country's detention centers. /VCG Photo

Surrounded by adults, the children sit alongside a cage. In the detention center at the border, hundreds of young migrants are grouped behind metal wires which were recently described by US media outlets as a “batting cage”. /VCG Photo

"We’re trying to demonstrate what it’s like in the children’s cell. They’re kept in like, five in one cell and it looks like it’s a dog pound. It’s horrible,” Lorenzo Morales, one of the protesters, said. /VCG Photo

A total of 1,173 migrant children have been taken away from their parents since the announcement of the “zero tolerance” policy in May. /VCG Photo
