New York Attorney General Letitia James is spearheading a coalition of 20 attorneys general in filing a lawsuit against the Trump administration in an effort to halt the administration’s plans to dismantle the Department of Education and lay off approximately 50% of its workforce.

New York Attorney General Letitia James and 20 other state attorneys general sued the Trump administration on Thursday to halt mass layoffs at the U.S. Education Department, charging it would effectively dismantle an agency without congressional authorization.

The lawsuit alleges the layoffs are so severe the department “can no longer function, and cannot comply with its statutory requirements.”
