'Uncharted territory': Ongoing shutdown threatens food aid for 42 million people

States are preparing for a spike in demand at food banks, like this one inside a church in Eagle River, Alaska, if food aid benefits through the Supplemental Nutrition Assistance Program, or SNAP, are cut off or disrupted because of the federal government shutdown.

SNAP, the country's largest anti-hunger program, dates back to the Great Depression and has never been disrupted this way. Most recipients are seniors, families with kids, and those with disabilities.
