More than 40 million Americans will stop receiving food stamps on 1 November, as the US government shutdown enters its fifth week. The Department of Agriculture says the Supplemental Nutrition Assistance Program (Snap) will be suspended until Congress reopens the government. While the Trump administration argues the department does not have the legal authority to use a $5bn contingency fund to continue the aid, Democrats disagree, and two dozen states have sued the government to force the program to continue.
