In 1978, a shirtless 18-year-old Rahm Emanuel demonstrated against a neo-Nazi rally in Chicago, and a few brief seconds were caught on camera.
As Malooley pointed out, the cameo is significant because it's one of the few images of Emanuel as a young adult and one of the few looks at his involvement in activism.
Emanuel faces Cook County Commissioner Jesus "Chuy" Garcia in Chicago's mayoral runoff election April 7. According to a Chicago Tribune survey, Emanuel leads 51 percent to 37 percent with 11 percent undecided.
