The Supreme Court has extended an order blocking full SNAP payments. The high court’s decision Tuesday came amid signals that the government shutdown could soon end and food aid payments resume — though exactly when is unknown. The order keeps in place at least for a few more days a chaotic situation. People who depend on the Supplemental Nutrition Assistance Program to feed their families in some states have received their full monthly allocations, while others have received nothing. SNAP helps 42 million Americans buy groceries. The order will expire just before midnight Thursday.
