A second federal judge in two days has blocked President Donald Trump’s effort to end birthright citizenship for the children of parents who are in the U.S. illegally, decrying what he described as the administration's attempt to ignore the Constitution for political gain.

President Trump is seeking to end birthright citizenship in the United States. What is it, which other countries apply the policy and who would be affected by the order?

On Thursday, U.S. District Judge John Coughenour, in Washington state, likewise issued a preliminary injunction, writing that the Trump administration’s position on birthright citizenship is “unavailing and untenable” and calling birthright citizenship “an unequivocal Constitutional right” that the president can’t change with an executive order.
