President-elect Barack Obama takes questions from reporters Friday in his first post-election news conference.
"I do not underestimate the enormity of the task that lies ahead," Obama told reporters at the Hilton Hotel in Chicago, Illinois. "We have taken some major action to date, and we will take further action."
Obama said that passing a stimulus package will be his first move if the lame-duck Congress fails to do so before he takes office January 20.
"It's not going to be easy for us to dig ourselves out of the hole that we're in," he said, flanked by Vice President-elect Joe Biden and members of his transition economic advisory board.
"But America is a strong and resilient country, and I know that we will succeed if we put aside politics and partisanship."
Obama pointed to Friday's release of unemployment figures and bad news from the auto industry as part of the reason that his administration will have to move quickly on the economic crisis. Watch Obama lay out his economic plan »
"We are facing the greatest economic challenge of our lifetime, and we are going to have to act swiftly to solve it," Obama said.

Obama said he would work together with Bush in bipartisan spirit to help the country move forward.
Responding afterward to the news conference, one GOP lawmaker said he was "encouraged by Barack Obama's idea that it is time to put the partisan politics aside and work to help us all."
"We have a difficult situation in front of us, and it is impacting individuals at the heart of their being," Sen. Tom Coburn, R-Oklahoma, said on CNN.

"We need a rescue plan for the middle class that invests in immediate efforts to create jobs and provide relief to families that are watching their life savings disappear."
He vowed to extend unemployment benefits for workers, to help families avoid foreclosure and to aid small businesses and strapped state and municipal governments as well as the U.S. auto industry, which has been pounded by plummeting sales.
"The auto industry is the backbone of American manufacturing," he said, promising that his transition team will work to "help the auto industry adjust."
On Friday, General Motors Corp., the nation's largest automaker, reported a huge loss much worse than expected -- $4.2 billion -- and warned it's in danger of running out of cash in the coming months. Ford Motor Co. also reported Friday a $3 billion operating loss in the latest quarter.

On the foreign affairs front, Obama reiterated that he believes a nuclear-armed Iran would be "unacceptable," but he said any U.S. response to Tehran would not be in a "knee-jerk fashion." Obama said he would help mount an international effort to keep Iran from becoming a nuclear threat. iReport.com: What's your message for Obama?
