A federal judge has temporarily blocked President Donald Trump’s executive order ending the constitutional guarantee of birthright citizenship regardless of the parents’ immigration status.

In a Washington state federal court Thursday a judge called President Trump's executive order seeking to end birthright citizenship for undocumented migrants "blatantly unconstitutional," temporarily blocking it . On Capitol Hill, the president's allies introduced a bill to make it law.

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