Sen. Bernie Sanders: American people 'want a political revolution'

At the PBS NewsHour Democratic Debate Thursday in Milwaukee, Sen. Bernie Sanders' opening remark touched on what he calls a "corrupt" campaign finance system, a "rigged economy" for average American workers and a "broken criminal justice system" in the United States.

"I think what our campaign is indicating, is that the American people are tired of establishment politics, tired of establishment economics," said Sanders. "They want a political revolution."
