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.

A federal judge in Rhode Island blocked the Trump administration from using states’ cooperation with immigration efforts as a condition for receiving transportation funds.

The Transportation Department lacks the authority to require the states to cooperate with ICE, the judge ruled.
