Fiscal cliff? Not to worry, says Warren Buffett

President Barack Obama must be willing to continue pushing for higher taxes on the wealthy, even if it triggers a "fiscal cliff" leading to automatic onset of tax increases and spending cuts beginning Jan. 1, super-investor Warren Buffett told CNN Wednesday.

The U.S. economy is "resilient" enough to weather it for a month or two, he said, shrugging off Congressional Budget Office warnings that failure to address the problem by Dec. 31 could lead to a recession.
