A federal judge on Thursday blocked the Trump administration from withholding billions of dollars in transportation funds from states that don’t agree to participate in some immigration enforcement actions.

Twenty states sued after they said Transportation Secretary Sean Duffy threatened to cut off funding to states that refused to comply with President Donald Trump’s immigration agenda. U.S. District Judge John McConnell Jr. barred federal transportation officials from carrying out that threat before the lawsuit is fully resolved.

“The Court finds that the States have demonstrated they will face irreparable and continuing harm if forced to agree to Defendants’ unlawful and unconstitutional immigration conditions imposed in order to receive federal transportation grant funds,” wrote McConnell, the chief judge for the federal district of Rhode island. “The States face losing billions of dollars in federal funding, are being put in a position of relinquishing their sovereign right to decide how to use their own police officers, are at risk of losing the trust built between local law enforcement and immigrant communities, and will have to scale back, reconsider, or cancel ongoing transportation projects.”
