Workers and civil rights activists are headed to Baltimore this weekend for a two-day Poor People’s Campaign and March to demand an end to police brutality, mass incarceration and austerity and to continue the work of Rev. Dr. Martin Luther King Jr. This weekend marks the 45th anniversary of the Poor People’s March on Washington on May 12, 1968. King helped launch the campaign but was assassinated weeks before the march on April 4, 1968. His widow Coretta Scott King and thousands of others marched on that Mother’s Day weekend to call for an end to poverty. This weekend, marchers will walk 41 miles, from Baltimore to Washington, D.C.
