Fox News host Neil Cavuto hammered outgoing Rep. Michele Bachmann (R-MN) on Wednesday over House Republicans' threat to sue President Barack Obama, accusing them of engaging in political theater that they know will not go anywhere in the courts.

"You're conflating issues and you're being silly," Cavuto told Bachmann. "Where was your rage when Democrats were going after President Bush on the same use of executive orders? Because I think you knew then that that was a waste of time then and I think you know in your heart of hearts this is a waste of time now. There are far more important things that I think you guys have to be addressing than filing lawsuits past each other."

"I'm not the one talking about that," Bachmann countered. "What I am saying is that what's very important is the president trying to establish lawlessness in the United States."

"Democrats said George Bush did the same, congresswoman," Cavuto said, before calling the suit a "waste of time."

House Speaker John Boehner (R-OH) raised the prospect of a lawsuit against Obama earlier in the day, saying it needed to be done to protect Congress' rights against what Republicans have described as constant overreach during Obama's presidency.

But, though Boehner said the lawsuit was not meant to lead toward impeachment proceedings, Bachmann put that option on the table during her interview with Cavuto.

"What we need to do is defund the executive branch, number one, and then impeach executive branch officials who have broken the law," she said, before Cavuto cut her off.

"Think about what you're saying -- defund the executive branch?" he said. "Congresswoman, if Democrats had said, 'We're gonna defund President Bush,' you would have laughed at them, and I think Democrats would be in their right mind to laugh at you now."
