WASHINGTON (AP) — The federal government is heading toward a shutdown this weekend that will disrupt many services, squeeze workers and roil politics. It comes as Republicans in the House, fueled by hard-right demands for deep cuts, force a confrontation over federal spending. While some government entities will be exempt, others will be severely curtailed. Social Security checks, for example, will still go out. But federal agencies will stop all actions deemed non-essential. And millions of federal employees, including members of the military, won’t receive paychecks. The shutdown will begin Oct. 1 if Congress is not able to enact a funding plan.
