Memorial service held in San Francisco for Asian-American mayor

Fire trucks suspend an American flag across the street from San Francisco City Hall as the casket containing the body of Mayor Ed Lee lies in repose in the rotunda on Friday, December 15, 2017. Lee died on Tuesday. He was San Francisco's first Asian-American mayor and presided over the city as it climbed out of a recession and into a boomtown driven by tech. [Photo: AP/Ben Margot]
