WAUKESHA, Wis. — Scott Walker appeared to take aim at the national minimum wage on Monday evening, referring to it as one of many "lame ideas" pushed by Democrats.

Walker's comment came in a lengthy interview with Fox News's Sean Hannity immediately following a speech formally announcing his entrance into the 2016 presidential race. Walker said the next president needs to speak the language of the industrial Midwest and connect with the working class.

"The left claims that they're for American workers and they've just got just really lame ideas — things like the minimum wage," Walker said. "Instead of focusing on that, we need to talk about how we get people the skills and the education and the qualifications that they need to take on the careers that pay far more than the minimum wage."

There has been a national debate over the minimum wage, which is $7.25 per hour for most workers. A number of cities and states have increased their minimum wages, often at the urging of Democrats. Republicans often oppose the measures on the grounds that they would burden struggling businesses. Hillary Rodham Clinton, the Democratic frontrunner, called for a higher minimum wage during an economic policy speech on Monday. U.S. Sen. Bernie Sanders of Vermont, who is also running for president, has called for a $15 per hour baseline.

A spokeswoman for Walker's campaign has yet to respond to a request for comment.
