A federal judge Thursday blocked President Donald Trump’s executive order outlawing birthright citizenship —the policy automatically giving citizenship to anyone born in the U.S.—and declared it “blatantly unconstitutional,” as legal experts widely believe the president does not have the power to change the policy on his own.

A Seattle-based federal judge granted a request from the Washington Attorney General's Office for a temporary restraining order to delay an executive order that could reinterpret the rules of birthright citizenship issued by President Donald Trump.
