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

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.

“Protecting the Meaning and Value of American Citizenship”—better known as the birthright citizenship executive order —attempts to cancel the 14th Amendment to the US Constitution. Getting rid of constitutional amendments via executive order is new, and, for me at least, “the worst.”
