"He brings extraordinary management skills, great political savvy, an impeccable record of integrity," Obama said, adding — perhaps in answer to grumbling from some members of Congress that Panetta has no direct experience in intelligence-gathering — that "he is somebody who obviously was fully versed in international affairs crisis management, and had to evaluate intelligence consistently on a day-to-day basis."

With Democrats controlling the House and Senate, a version of Obama's stimulus plan seems likely to become law within a few weeks. He has promised Republicans a say in the process, saying bipartisan support is vital.

As an Illinois senator for four years, Obama obtained federal money for several local projects in large spending bills. But some lawmakers have abused the earmarking process, he said during his two-year campaign.

Obama's proposed Economic Recovery Accountability and Transparency Board is to include members the administration deems relevant to helping the country rebound from the year-old recession, as well as inspector generals of agencies including transportation, defense, energy, education and health and human services.

Outside appointees with expertise in economics, public finance, contracting, accounting, auditing and other areas will advise the board. It will hold public meetings and issue financial reports to Congress on how the money is being used.

The new Web site will allow taxpayers to track where money is being spent while also showing the administration's estimate of how the money is affecting individual communities and the economy overall.

Obama met Monday with congressional leaders to seek backing for his economic plan. It could cost $775 billion over two years, his advisers say, though they say they think add-ons by lawmakers could raise the price to $850 billion. Obama's advisers say an $850 billion plan could generate about 3.2 million jobs by the first quarter of 2011.

His proposal includes tax cuts of up to $300 billion — including $500 for most individuals and $1,000 for couples if one spouse is employed — as well as more than $100 billion for businesses.

Some $77 billion would be used to extend unemployment benefits and to subsidize health care for people who have lost their jobs. The rest would go toward job-creation projects such as rebuilding roads and bridges and toward long-term goals like alternative energy programs.

Obama spoke with reporters after meeting with his chief of staff, Rahm Emanuel; Timothy Geithner, his Treasury Secretary-designate; budget director Peter Orszag and his top deputy, Rob Nabors; Christina Romer, chosen to head the Council of Economic Advisors; and Lawrence Summers, a former Treasury secretary who will head Obama's National Economic Council.
