WASHINGTON (AP) — President Barack Obama says he won't sign another temporary government funding bill after the current one expires on Dec. 11.

He is instead demanding a budget agreement with Republicans controlling Congress that would lift a freeze on the budgets of both the Pentagon and domestic agencies.

Obama said at a White House news conference that he "won't sign another shortsighted spending bill" and that the U.S. can't cut its way to prosperity.

Budget talks have just started and are taking place amid considerable turbulence on Capitol Hill. Tea party conservatives have forced out House Speaker John Boehner and are skeptical of a deal to replace tight caps on spending set by a 2011 budget deal.
