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 Donald Trump moved to end a decades-old immigration policy known as birthright citizenship when he ordered the cancellation of the constitutional guarantee that U.S.-born children are citizens regardless of their parents’ status.
