A federal judge agreed Thursday to issue a new nationwide block against President Donald Trump’s executive order seeking to end birthright citizenship. The ruling from US District Judge Joseph Laplante is significant because the Supreme Court last month curbed the power of lower court judges to issue nationwide injunctions,

The ACLU’s class-action lawsuit seeks to protect children born to undocumented parents from President Trump’s order.

The judge also granted the case class-action status after the Supreme Court limited the ability of judges to block orders nationwide through other means.
