Sen. Bernie Sanders on Wednesday rallied outside the U.S. Capitol with low-wage federal workers who had walked off the job in support of raising the minimum wage fo federal contractors to $15 per hour. "What America is supposed to be about is if you work 40 hours a week, you make enough money to feed your family," Sanders told the crowd. "A great nation will not survive, in my view, when so few have so much and so many have so little."
