 From ABC News. I'm Daria Albinger. History from the High Court. The Supreme Court justices rule on former President Trump's immunity claim. More from ABC's Stephen Portnoy in Washington. Chief Justice John Roberts wrote the opinion himself, saying that while a president is not above the law, a chief executive does enjoy absolute immunity for official acts that are core to his constitutional powers. And he's entitled to the presumption of immunity for his other official acts.
