David Chavern, Executive Vice President and Chief Operating Officer of the U.S. Chamber of Commerce, explains what it means for the United States, it's citizens, and the economy to go over the "Fiscal Cliff." He urges Congress to act immediately to prevent current tax rates from expiring and across-the-board federal spending cuts from taking effect on January 1, 2013.  According to the nonpartisan Congressional Budget Office and many economists, the combination of these tax hikes and spending cuts will plunge the U.S. economy back into a recession in 2013.
