As the Trump administration continues to decimate the U.S. Department of Education, a coalition of states is challenging the shifting of many of the department’s core functions to the U.S. Department of Labor and three other federal agencies.

The Democratic attorneys general from 20 states and other groups, including unions and school districts, initially sued to stop mass layoffs at the DOE. They filed an amended lawsuit on Nov. 25 arguing that federal laws require that the department carry out its own programs and that the administration cannot reorganize it to such an extent. President Donald Trump issued an executive order in March for U.S. Secretary of Education Linda McMahon to “take steps to facilitate the closure” of the DOE.

The DOE, which laid off about half of its staff this year, developed agreements with the U.S. Department of Labor and the departments of Health and Human Services, the Interior and State to take over many of its key functions.

The Labor Department will administer most of the more than $20 billion in federal funding for K-12 schools — including Title I money for high-poverty schools — and manage many programs that were overseen by the DOE’s Office of Postsecondary Education.
