BOSTON — Massachusetts Attorney General Andrea Joy Campbell is back in court against President Donald Trump — again.

This time, Campbell is leading a 22-state lawsuit accusing the Trump administration of “starving families” by freezing food-stamp payments during the federal shutdown. The suit targets the U.S. Department of Agriculture and Secretary Brooke Rollins, claiming the agency unlawfully suspended the Supplemental Nutrition Assistance Program (SNAP), which helps 42 million Americans — including more than one million in Massachusetts — buy groceries.

“More than one million people in Massachusetts rely on SNAP to put food on the table,” Campbell said. “Despite having the money to fund SNAP, the Trump Administration is creating needless fear, angst and harm for millions of families and their children especially as we approach the holidays.”

The USDA warned states that without a budget deal, it couldn’t pay full November benefits. Campbell’s coalition calls that false, saying the agency has billions in contingency funds meant for moments like this — and accuses Trump officials of making a “deliberate, illegal and inhumane choice” not to use them.

The administration argues its hands are tied by law: contingency dollars can’t be spent on monthly benefits without congressional approval.

Campbell’s filing adds to a growing list of legal battles she’s waged against Trump. The lawsuit says the SNAP freeze violates the Administrative Procedure Act and will strain food banks and small grocers while pushing families into emergency aid programs.

In Massachusetts, more than one million people could lose food benefits this week. Nearly 60 percent of recipients are children or seniors, and another 31 percent are people with disabilities.

Trump’s allies call the move fiscal discipline; Campbell calls it cruelty. Either way, the Bay State’s top Democrat has once again positioned herself opposite the president — and she’s not backing down.
