The White House Office of Management and Budget (OMB) is telling federal agencies to draw up reduction-in-force (RIF) plans ahead of a possible government shutdown on Oct. 1, according to an internal memo obtained by Fox News.The guidance says agencies must consider issuing RIF notices to employees working on programs that are not legally required to continue if funding lapses."With respect to those Federal programs whose funding would lapse and which are otherwise unfunded, such programs are no longer statutorily required to be carried out," the memo states.Under the guidance, RIF notices would be issued on top of furlough notices and should go to all employees tied to the affected programs.GARBAGE COLLECTION, TOURS TO BE SUSPENDED ON CAPITOL HILL IF THERES A GOVERNMENT SHUTDOWNAgencies would later revise those plans once Congress approves fiscal year 2026 appropriations, keeping only the staff needed for core statutory functions.The memo notes that while Congress has usually passed short-term funding bills on a bipartisan basis, they believe this year is different.The same memo accuses Democrats of breaking that trend and pushing for "insane demands, including $1 trillion in new spending," which it says could force a shutdown.SCOOP: GOP RAMPS UP SHUTDOWN FIGHT, TARGETS 25 VULNERABLE DEMOCRATS IN NEW AD BLITZLast week, the House passed H.R. 5371, described as a clean continuing resolution (CR) that would extend current funding through Nov. 21.
