Judy Woodruff:

With the government shutdown now in its 27th day, many federal programs have been affected, including food stamps.

So far, there is no major lapse in benefits used by nearly 39 million people each month. That's because of the U.S. Department of Agriculture. It found a way to pay SNAP benefits, as they are called, earlier than normal.

February benefits, awarded through a debit-style card used at stores, are being paid out this week. Several states, including California and Florida, are warning users to be careful and make sure they manage to make the money last longer.

For 2,500 retailers, the problem is already here. That's because those stores needed to renew a license for the Electronic Benefit Transfer, or EBT debit card program, and they failed to meet a deadline before the shutdown. Those renewals, required every five years, are on hold.
