WASHINGTON -- President Barack Obama called on Congress to stop taxpayer-funded subsidies for oil companies, and the Senate promptly ignored him Thursday.Senators voted 51 to 47 to end debate on a bill that would do what Obama asked, thus failing to reach the 60 votes needed to end a filibuster.The rebuff came just an hour after the president took to the Rose Garden to make his appeal, arguing that with oil prices hovering at around $100 a barrel and oil companies netting billions of dollars each financial quarter, there's little reason to give taxpayer-funded aid to the U.S.
