Rev. Al Sharpton is planning a national march on Washington next week following a grand jury decision not to indict a New York City police officer in the death of Eric Garner.

Sharpton said at a press conference Wednesday night at his National Action Network headquarters in Harlem that the march will take place on Saturday, Dec. 13.

“It’s time for a national march for a national crisis,” Sharpton said.

He continued: “We are not advocating violence, we are asking that police violence stop.”
