President-elect Barack Obama's office announced the details of his major speech on the economy Wednesday afternoon, advocating "urgent action" on his economic stimulus plan. The speech will be held at 11 a.m. today at George Mason University in Fairfax, VA., located just outside of Washington, D.C.

Obama will focus on the stimulus plan he is negotiating with Congress, "[making] the case for urgent action on an American recovery and reinvestment plan that will save or create 3 million jobs while investing in priorities like health care, energy and education that will jump-start economic growth," the transition team said in a release.

The president-elect is taking his appeal straight to the public after lobbying on Capitol Hill on Monday for his stimulus plan, which is expected to reach $775 billion over two years. Get more details on Obama's economic stimulus plan.
