President Donald Trump's executive order seeking to end birthright citizenship will face its next legal hurdle this week when three separate federal judges hold hearings to consider whether to block the order.

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.

After being sworn in as president on Monday, Jan. 20, President Donald Trump filed an executive order to terminate birthright citizenship for children of undocumented immigrants.
