A U.S. Supreme Court ruling last week could enable a Trump executive order restricting birthright citizenship. It could change who is considered a U.S. citizen, depending on what state a child is born in and their parents' immigration status.

Three days after the Supreme Court said litigants attempting to get court orders broadly blocking President Donald Trump’s policies must do so through class action lawsuits, an administration lawyer said it plans to oppose such legal maneuverings in cases challenging the executive order seeking to end birthright citizenship.
