Memorial service held in San Francisco for Asian-American mayor

Mourners walk past flowers left for Mayor Ed Lee as they enter San Francisco City Hall rotunda to view Lee lying in repose 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]
