CONCORD, New Hampshire − A federal judge again barred President Donald Trump's administration from enforcing his executive order limiting birthright citizenship nationwide after the Supreme Court restricted the ability of judges to block his policies using nationwide injunctions.

The Trump administration could move ahead with mass layoffs.

Granting class status would empower Laplante, if he is inclined to do so, to issue a fresh judicial order blocking implementation of the Republican president's policy nationally.

The Supreme Court on Wednesday refused to allow Florida to enforce a state law that makes it a crime for anyone who entered the United States illegally to enter or remain in the state.

Williams ruled that Florida's law conflicted with the federal government's authority over immigration policy.
