San Francisco Mayor Edwin Lee, a former civil rights attorney who became the first Asian-American to serve in the city’s top post, died early Tuesday — hours after appearing at a public event — at a city hospital at age 65, his office said.

Lee, who had been mayor since 2011, had suffered a heart attack while shopping at a Safeway grocery store Monday night, said US House Minority Leader Nancy Pelosi, who represents San Francisco in Congress. Lee’s office didn’t release his cause of death.
