Rep. John D. Dingell, D-Mich., who becomes the longest-serving member of Congress on Friday, has never shied away from a constituent event, even those at which there is a dearth of voting-age participants. Such is certainly the case in this late 1980s photo taken at Custer Elementary School in Monroe, Mich., which also happens to feature Roll Call Managing Editor Katie Smith. That’s her in the peach shirt immediately to the left of Dingell.
