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.

A judge in Maryland heard arguments over the timing of the president’s order, which is set to go into effect in 30 days.
