There are now more than 10,000 migrant children in U.S. government custody.
These are teenagers who fled violence in Central America. And children who were separated from their parents after they crossed the U.S.-Mexico border illegally.
How the children should be cared for and what happens to them is part of a growing clash between the Trump administration and advocates.
One of these young migrants made the long trek from El Salvador last year and turned herself in to U.S. authorities at the border.
