LAS VEGAS — Hillary Rodham Clinton and Sen. Bernie Sanders, have clashed over U.S. involvement in the Middle East, gun control and economic policy in the first Democratic presidential debate Tuesday.

On the nation's economy, Sanders derided what he called "a casino capitalist process by which so few have so much." Clinton said it would be a "big mistake" for the U.S. to turn its back on the economic system that built the American middle class.

Sanders came to Clinton's defense on the issue of her use of a private email server while secretary of state. Sanders passed on an invitation to criticize Clinton on the matter. He told Clinton: "the American people are sick and tired of hearing about your damn emails." That drew a cheer from the crowd as well as a "thank you" and a handshake from Clinton.

Martin O'Malley; Jim Webb and Lincoln Chafee also took part in the debate.
