Eighteen Democratic attorneys general filed a lawsuit on Monday challenging President Donald Trump’s executive order restricting wind projects as a part of the U.S. energy infrastructure.

New York Attorney General Letitia James led a coalition of Democrats from 17 states and Washington, D.C., alleging that a memorandum Trump issued during his first day in office to halt wind projects on federal lands is unlawful. The order temporarily blocked all lease sales for offshore wind projects and paused any new approvals, permits, leases, or loans both on and offshore.
