Protesters turn their backs on Bloomberg during 'Bloody Sunday' anniversary church service

Michael Bloomberg received a frosty reception in Alabama just two days before Super Tuesday.

The billionaire former New York City mayor, 78, and Joe Biden, 77, visited Brown Chapel African Methodist Episcopal Church in Selma on Sunday morning to mark the 55th anniversary of “Bloody Sunday," when civil rights activists violently clashed with Alabama State Troopers on Edmund Pettus Bridge.

"The people of Selma will struggle for the soul of the nation," Bloomberg said during his speech as a diverse handful of protesters in the audience stood up and turned their backs to him.

Bloomberg has faced scrutiny for racially-tinged comments he's made in the past about policies, such as stop and frisk and "redlining," which critics have panned as being discriminatory to minority communities.
