US President Donald Trump vowed Wednesday to fight a federal court ruling halting his revised temporary ban of refugees and nationals from six Muslim-majority countries, describing the decision as "judicial overreach."

"The law in the constitution gave the president the power to suspend immigration when he deems it to be in the national interest of our country," he said at a rally in Nashville, Tennessee, following the decision by the Hawaii court.

He told the cheering crowd that his administration would "take our case as far as it needs to go, including all the way up to the Supreme Court. We are going to win."
