Within hours of his inauguration, President Donald Trump signed an executive order that would withhold U.S. citizenship from the children of some immigrants born in the United States, calling the order a “big one.” The executive order would end a right that the U.S. Constitution has guaranteed for more than 150 years.

The federal judge reignited the legal standoff over President Trump’s efforts to deny citizenship to children born to undocumented parents.

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