Donald Trump urged the Supreme Court on Thursday to curtail the ability of federal judges to issue injunctions blocking his administration's actions nationwide, marking the latest sign of tension between the Republican president and the U.

Despite the White House’s repeated attacks on federal Judge James Boasberg, the Trump administration remains confident it will prevail in ongoing litigation about the president’s use of executive power.

The Supreme Court seems to be in no hurry to address an issue that has irritated Republican and Democratic administrations alike: the ability of a single judge to block a nationwide policy.
