Washington — After consulting with Barack Obama, Democratic leaders are likely to call Congress back to work after the election in hopes of passing legislation that would include extended jobless benefits, money for food stamps and possibly a tax rebate, officials said Saturday.

The bill's total cost could reach $150 billion, these officials said.

The officials stressed that no final decisions have been made. They spoke on condition of anonymity, saying they did not want to pre-empt a formal announcement. House Democrats have announced plans for an economic forum on Monday "to help Congress develop an economic recovery plan that focuses on creating jobs and strengthening our economy."

Democrats said Obama's campaign has been involved in discussions on a possible stimulus package. The party's presidential candidate, running ahead in the polls, has outlined his own proposals for stimulating the economy.

Democrats are increasingly confident of capturing the White House and increasing their majorities in the House and Senate on Nov. 4.

If they are successful, a lame-duck session of Congress two weeks later would allow them to start work on a response to the credit crunch that has sent stock prices plummeting and also threatens to trigger a deep recession. It often takes two or three months for a new Congress to begin turning out legislation, particularly when a new president is settling into the White House.

On the other hand, by attempting to pass legislation next month, Democrats would have to negotiate with President Bush, whose term runs until Jan. 20, 2009. Additionally, Senate Republicans, with 49 seats, could block any measure they opposed.

House Speaker Nancy Pelosi told reporters in Denver last Wednesday a $150 billion stimulus package is necessary and she may call the House back into session after the election. Her spokesman, Brendan Daly, added, "Congress just worked in a bipartisan way with the administration to pass an economic rescue plan to help stabilize our financial markets, and we must now work together to pass a jobs creation and economic recovery stimulus package."

In the Senate, Majority Leader Harry Reid of Nevada has announced a post-election session beginning Nov. 17 to consider public lands legislation. His spokesman, Jim Manley, issued a written statement that said "recent developments only reinforce the need for additional action to reinvigorate the economy." He added, "no decisions have yet been made on how to proceed."

An Obama spokesman, Bill Burton, said the campaign is monitoring the situation.

The candidate has said previously he favors $25 billion to help states meet their own needs, another $25 billion for roads, bridges and other infrastructure, and $65 billion for tax rebates paid for by a windfall profits tax on oil.
