A group of 20 mostly Democratic-led US states filed a lawsuit on Wednesday seeking to block the Trump administration from terminating a multibillion-dollar grant program that funds infrastructure upgrades to protect against natural disasters. The states said they would seek a preliminary injunction requiring the program to be reinstated while the case proceeds. The lawsuit is the latest attempt by states to rebuke the Trump administration’s approach to disaster funding. Many of the same states sued the administration in May over a policy tying grant funding for emergency preparedness to states’ cooperation with federal immigration enforcement. Massachusetts’ attorney general, Andrea Campbell, in a statement said the recent flooding in Texas, which caused more than 130 deaths, has made clear how critical federal funding is to helping states prepare for natural disasters.
