A federal judge questions the Trump administration on implementation plans for controversial birthright citizenship executive order as advocacy groups file class action lawsuits in response.

A federal judge has ordered the Trump administration to explain how it will enforce President Trump's executive order seeking to eliminate birthright citizenship.

President Donald Trump's administration will not deport children deemed ineligible for U.S. citizenship until his executive order curtailing birthright citizenship takes effect on July 27, a government lawyer said on Monday after being pressed by two federal judges.
