FILE - In this June 24, 1968 file photo, Rev. Ralph Abernathy, leader of the Poor People's Campaign, looks through the barred window of a bus after he was arrested in Washington for leading a group of demonstrators onto the grounds of the U.S Capitol. Thousands of anti-poverty activists have launched a campaign in May 2018 modeled after Rev. Martin Luther King Jr.'s Poor People's Campaign of 1968. Like the push 50 years ago, advocates are hoping to draw attention to those struggling with deep poverty from Appalachia to the Mississippi Delta, from the American Southwest to California's farm country.
