Justice Ruth Bader Ginsburg, "the Notorious RBG," is "a feminist icon" and at 85, "the oldest justice on the Supreme Court," Stephen Colbert said on Wednesday's Late Show. "But she has made it very clear that she has no interest in retiring. Which is good — please, just hang in there for 3-7 more years." She is ensuring her longevity by keeping in shape with a really hard workout, "which is surprising," Colbert said.
