In the few days since he returned to the White House, President Donald Trump’s sweeping executive orders and mass pardons have shattered political and legal norms. But one order is in a category of its own.

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.

It marks the first court hearing on the executive order, signed by Trump on Monday, which seeks to end the right to citizenship for children who are born in the US to parents who are in the country illegally or temporarily.
