Fox News' Neil Cavuto cut to commercial during a heated interview with Rep. Eddie Bernice Johnson where the congresswoman told him to “shut up for just a second” and he later called their discussion “a total waste of time.”

The Texas Democrat and Cavuto on Thursday argued over the fiscal cliff battle for several minutes before the interview came to an abrupt end. Cavuto repeatedly asked Johnson what things she would cut and the congresswoman countered that what should be discussed is "revenue generation."

“No, you told me things you’d do to raise taxes. That’s what you told me. Credits, allowances, that sort of stuff. That’s what you told me,” Cavuto said.

“You’ve got to talk about revenue generation,” the congresswoman replied.

“I know that, but it’s 100 percent of what you’re talking about, Congresswoman,” Cavuto said.

“It is not 100 percent of what I’m talking about. If you’d shut up for just a second, I would try,” Johnson said.

Cavuto then jumped in, saying, “You gotta tell me one thing you’d cut. I beg you Congresswoman, one thing you would say, I would cut this. What would it be?”

When Johnson did not reply with anything more than “you" and a pause, Cavuto asked, “You don’t know, do you?”

 “Well, yes I do know, but I have to have time to explain it. I can’t tell you I’m going to walk in and cut this and cut that. First of all, it has to have some type of dialogue. We have not had that,” she said.

The two continued to go back and forth until Johnson said that Democrats have already said what cuts their party is willing to consider, and with that, Cavuto was done with the interview.

“Well, you haven’t done that,” he replied. “You haven’t done that. You haven’t done that. But hope springs eternal máam, and Congresswoman I want to get you back, but this was a total waste of time.”
