A surge of undocumented immigrants are pouring into the United States. It's a situation that is fast becoming one of the biggest political challenges President Obama has ever faced.
Obama made an emergency $3.7 million funding request to handle the crisis - almost twice as much as what the administration had previously signaled it needed.
One reason this crisis is so dire is a historic flood of children are beingÂ caught crossing the Southwest border.
In 2009, about 3300 children from El Salvador, Guatemala and Honduras were caught by Border Patrol agents, according to the Department of Homeland Security. So far, this year, 40,000 children were caught.
CNN's Kyung Lah is at the border with the story of one Guatemalan family and the frightening world they left behind.
