Republican U.S. Rep. Michele Bachmann and Fox News host Neil Cavuto tangled Wednesday during a debate on the House GOP plans to sue President Obama, alleging that he's failed to carry out laws passed by Congress.

Speaker John Boehner announced Wednesday that the Republican-led House will vote next month on legislation authorizing a lawsuit.

"Has the president overreached with his power? Absolutely he has," Bachmann said. "The Constitution is a stop sign for the president … You can't do anything you want."

Cavuto called the proposed vote and lawsuit an "enormous waste of effort."

Later in the five-minute interview, Bachmann suggested Republicans vote to defund the executive branch.

"Make it hurt," she said. "If they don't have money, they don't have power."

In response, Cavuto accused Bachmann of "being silly."

"I think you know in your heart of hearts this is a waste of time now. There are far more important things you guys have to be addressing than filing lawsuits past each other," Cavuto said. "Think about what you are saying. The Democrats would be in their right mind to laugh you out."
