A political operative sounded the alarm on a Supreme Court justice whom he believes is President Donald Trump's chief enabler. During an episode of Court of History, journalist and former senior Clinton White House advisor Sidney Blumenthal explained the thinking behind a recent article he wrote for The Guardian about Supreme Court Justice Brett Kavanaugh. "And he's really the most politically attuned, the one who is acting most like a political operative, and the results are catastrophic." When Trump appealed a decision that blocked his tariffs, the Supreme Court sided with a lower court decision that called Trump's claims "unconstitutional," Blumenthal said. "He was playing the staffer to Trump," Blumenthal said.
