New York is leading a coalition of five states and the District of Columbia in a lawsuit against the Trump administration over its decision late last year to roll back Obama-era standards for school lunches, allowing higher levels of sodium and less whole grains, state Attorney General Letitia James announced Wednesday.

James said the Trump administration loosened those standards, which apply to 30 million schoolchildren, without public notice or the opportunity to comment, which allegedly violated the federal Administrative Procedure Act.

“Over a million children in New York—especially those in low-income communities and communities of color—depend on the meals served daily by their schools to be healthy, nutritious, and prepare them for learning,” James said. “The Trump administration has undermined key health benefits for our children—standards for salt and whole grains in school meals—with deliberate disregard for science, expert opinion, and the law.”
