As the U.S. has been inundated with a record number of illegal immigrants, the unaccompanied children crisis has also spiked. Unaccompanied children are those who cross illegally without a parent or guardian. The government typically pays to send them to a sponsor. But whistleblowers say the sponsors are vetted through little more than an honor system, and the kids are sometimes trafficked into the hands of criminals and gangs. In August, the Inspector General seemed to confirm the worst. In an urgent report, it said the government has lost track of more than 32,000 children over the last five years.
