In two cases brought to the high court, lower courts kept in place a preliminary injunction against President Donald Trump’s executive order that ended birthright citizenship. The high court case was docketed on Monday. In June, the Supreme Court reined in nationwide injunctions by some lower courts that had blocked the executive order rewriting birthright citizenship. Under birthright citizenship, all children born in the U.S. are considered citizens, regardless of their parents’ legal status, except for the children born to foreign diplomats. The Supreme Court has ruled on birthright citizenship many times, including a 1898 decision in which the justices upheld birthright citizenship in United States v. Wong Kim Ark.
