The money is specifically for certain things. If the Dept of Ag were to use it to cover SNAP they'd be committing a potentially criminal act in using money allocated for one purpose for something it isn't supposed to be used for by law. I've controlled budgets under the Federal Acquisition Regulations. You just can't move money allocated to one line item to another as you please. There are lots of rules and if you don't follow them, you could find yourself facing charges.
