Democratic front-runner Hillary Clinton on Monday praised her husband, Bill, and President Obama for arriving in the White House to "clean up the mess" left by Republicans, but an email from her campaign showed that wages under Obama have dropped -- and continue to do so.

"For 35 years, Republicans have argued that if we give more wealth to those at the top – by cutting their taxes and letting big corporations write their own rules – it will trickle down, it will trickle down to everyone else," she said in an economic address.

"Yet every time they have a chance to try that approach, it explodes the national debt, concentrates wealth even more, and does practically nothing to help hard-working Americans. Twice now in the past 20 years, a Democratic president has had to come in and clean up the mess. I think the results speak for themselves," she added.

But a wage and productivity graphic provided by her campaign showed wages down under Obama starting in 2010, the first time in 20 years. The economic data was credited to the Economic Policy Institute.

"You're working harder but your wages aren't going up," said the graphic.
