WASHINGTON (AP) — Republicans have to stop using “political math” and say how much they are willing to raise tax rates on the wealthiest 2 percent of Americans and then specify the spending cuts they want, Treasury Secretary Tim Geithner said in an interview that aired Sunday.

Just four weeks from the proverbial “fiscal cliff,” House Speaker John Boehner countered that Republicans have a plan for providing as much as $800 billion in new government revenue over the next decade and would consider the elimination of tax deductions on high-income earners. But when pressed on “Fox News Sunday” for precise details, the Ohio Republican declined to say.
