WASHINGTON — Federal worker unions have asked a judge to halt Trump administration actions that they say includes plans to cut 10,000 positions from the Federal Emergency Management Agency. Tuesday’s filing of a supplemental complaint alleged the Trump administration intends to cut thousands of federal workers this year across other agencies as well. That would effectively cut the agency by 10,000 federal workers over the next few months as the temporary workers’ terms expire. The administration has faced numerous lawsuits over its efforts to lay off federal workers, including from federal worker unions and from Democrat-led states. Democratic attorneys general have also sued over unilateral cuts to FEMA and other federal grant programs by the Trump administration.
