Twenty states had sued after federal transportation officials threatened to cut off funding to states that refused to comply with President Trump’s immigration agenda.

Attorneys general in 20 states, most led by Democrats, had sued the administration. Similar suits have been filed over funding for other programs.

“Defendents seek to hold hostage tens of billions of dollars of critical transportation funding in order to force the plaintiff states to become mere arms of the federal government’s immigration enforcement policies,” Delbert Tran of the California Department of Justice, who argued on behalf of the states, said.
