Missouri Democratic Sen. Claire McCaskill railed against the national debt, speaking in Kansas City as part of her “McCaskill on Main Street” tour on Wednesday. McCaskill said the debt would “put us in a position where we’re not a first-tier nation anymore,” calling it “irresponsible.”

“I do believe a $17 trillion debt is irresponsible. I do believe that,” McCaskill said, while adding that she supported raising the minimum wage and extending unemployment insurance.

McCaskill also spoke about the changes she says she’s seen in the influence of the federal government.

“We have ourselves doing things the federal government was never intended to do,” she said. “I mean, we weren’t supposed to be buying municipal firetrucks at the federal government, we’re doing that now. That’s not the way our Constitution was designed. We weren’t supposed to have the federal government paying for education. We are now doing a lot of that.”
