Benefits for the Supplemental Nutrition Assistance Program (SNAP) won't be distributed on Nov. 1, leaving millions of low-income families scrambling for food.

The U.S. Department of Agriculture (USDA) announced on its website that SNAP benefits won't be sent out come Nov. 1 because the program lacks the funding it needs during the ongoing government shutdown.

SNAP, also known as food stamps, is a federal program that provides 42 million Americans monthly benefits to afford healthy food.

SNAP benefits won't go out Nov. 1. 'The well has run dry,' USDA says.

"Bottom line, the well has run dry. At this time, there will be no benefits issued November 1," a message on USDA's website as of Oct. 27 says.
