WASHINGTON (AP) -- Congressional leaders and the Bush administration have reached a tentative deal on a bailout of imperiled financial markets that could cost taxpayers hundreds of billions of dollars. The House could vote on it Sunday and the Senate on Monday. House Speaker Nancy Pelosi announced the accord just after midnight Saturday and said it still has to be put on paper. Treasury Secretary Henry Paulson talked of finalizing the deal but added: "I think we're there." The aim of the deal is to prevent credit from drying up and causing a meltdown of the U.S. economy. http://www.cnn.com/2008/POLITICS/09/28/bailout.ap/index.html http://www.cnn.com/ Note the part about Senate not voting until Monday which means uncertainty in Sunday night trading.
