A federal judge is set to hear the first arguments in a multi-state lawsuit seeking to block President Donald Trump’s executive order ending the constitutional guarantee of birthright citizenship regardless of the parents' immigration status.

President Trump's executive order challenging birthright citizenship will face its first legal test in a Seattle courtroom Thursday.

The Trump administration is "twisting itself in knots" in trying to limit birthright citizenship and focus on deportations, argues New Jersey Attorney General Matthew Platkin.
