The Obama administration is emphasizing “fairness” over deficit reduction in its renewed pitch for the “Buffett rule” ahead of next week’s scheduled Senate vote.

Introducing a minimum 30 percent income tax on millionaires “was never our plan to bring the deficit down and get the debt under control,” Jason Furman, the principal deputy director of the White House National Economic Council, told reporters on a conference call Monday afternoon. “This is not the president’s entire tax plan. We’re not trying to say this solves all our economic problems, all our budget problems.”

Making the argument for the rule based on billionaire investor Warren Buffett’s argument that it’s wrong for him to pay a lower tax rate than his secretary, President Barack Obama said in the State of the Union address in January that paying the “fair share of taxes” was necessary for a “sense of shared responsibility. That’s how we’ll reduce our deficit.”
