Oil finished lower Thursday as doubts increased over political leaders' ability to strike a deal in budget negotiations.
Enthusiasm over the U.S. Federal Reserve's plan to boost the economy, announced Wednesday, was replaced by concerns that President Barack Obama and Republican leaders were as far apart as ever on reaching a budget deal before year's end. Without an agreement, significant tax increases and government spending cuts will automatically take effect.
That so-called "fiscal cliff" could pull the U.S. economy into recession, likely hurting demand for energy.
