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 Donald Trump is seeking to end birthright citizenship, a move to cut off a longstanding constitutional right that could leave hundreds of thousands of Texas children without legal status. The move has been questioned by legal scholars and it has already drawn lawsuits from the American Civil Liberties Union and a coalition of Democratic-led states.

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