Sen. Bernie Sanders received applause and praise from Senate Democrats at a closed-door lunch in which he made no promises to quit his presidential campaign, but urged the party to move to the left.

“It was a long one, and it was a good one,” Senate Minority Whip Richard Durbin, D-Ill., said of Sanders’ message to Democrats. “He believes that there is a basic feeling in America that politicians don’t understand the problems Americans are facing, like income inequality and the power of the banks, big money in politics and so on. And he really challenged us and said the question is whether the Democratic Party is going to be responsive to those issues.”
