Colorado's Attorney General has joined 20 other states in suing the president's administration to stop what they call the "illegal dismantling" of the U.S. Department of Education.

ALBANY — New York is seeking to halt President Donald J. Trump’s plan to scale down and eliminate the federal Department of Education. The state joined a lawsuit filed Thursday with 19 other attorneys general against the Trump administration, arguing that the authority to dismantle the department is held by Congress, not the White House.

The Trump administration cut about half the agency’s work force, saying the move would enable it to deliver services more effectively. The attorneys general called the layoffs “reckless and illegal.”
