Federal judge in New Hampshire stayed the order for seven days to allow the Department of Justice to appeal. He called birthright citizenship "the greatest privilege that exists in the world."

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

Trump’s executive order, signed in January, seeks to deny citizenship to children who are born to people who are living in the U.S. illegally or temporarily. It is part of the hard-line immigration agenda of the president, who has called birthright citizenship a “magnet for illegal immigration.”
