WASHINGTON (CNN) - Rick Davis, the new campaign manager of Sen. John McCain's presidential bid, said Tuesday the Arizona Republican's campaign is "moving forward."

"This campaign has always been about John McCain and his vision for reducing federal spending, defending traditional values, and winning the war against Islamic extremists," Davis said in a statement. "Today we are moving forward with John's optimistic vision for our country's future."

Davis' statement comes hours after key members of the campaign - including former campaign manager Terry Nelson - announced their resignations.
