Record number of families, cold reality at border

In a dusty lot along the U.S.-Mexico border fence, a single Border Patrol agent was stuck with few options and falling temperatures.

A group of 64 parents and children had waded through a shallow bend in the Rio Grande to turn themselves in to the agent on the U.S. side. He radioed for a van driver, but there were none available. By 2 a.m., the temperature was 44 degrees.

The agent handed out plastic space blankets. The group would have to wait.
