Although it is officially observed Monday, Sunday was the 83rd birthday of Martin Luther King, Jr., and President Obama and his family attended a service in Washington honoring the civil rights leader. In New York, Occupy Wall Street protesters hiked uptown to Riverside Church near Harlem for a star-studded candlelight vigil. Members of Rev. Al Sharpton’s National Action Network joined the protesters, and musicians like Patti Smith performed. A statement from Yoko Ono was read and hip hop mogul Russell Simmons also addressed the demonstrators, who say they hope to carry on King’s legacy through peaceful protests.
