The Senate parliamentarian has advised that a Republican proposal that would shift some food stamp costs from the federal government to the states would violate the chamber’s strict rules.

The GOP leadership is scrambling days before voting on the legislation is expected to begin. Trump wants the package passed into law by the Fourth of July.
