Supreme Court Justice Ruth Bader Ginsburg has issued a scathing assessment of a potential Donald Trump presidency, calling Trump a “faker” and saying, “I can’t imagine what the country would be—with Donald Trump as our president. … How has he gotten away with not turning over his tax returns? The press seems to be very gentle with him on that.” It is unusual for a sitting Supreme Court justice to speak out on presidential candidates, but Ginsburg has recently made on-the-record remarks to several news organizations. Ginsburg’s most recent criticisms came Monday in an off-camera interview with CNN. Trump responded by calling on Ginsburg to resign, tweeting, “Her mind is shot.”
