President Bush is now backing off a forecast made by his own economic advisers that the economy will add 2.6 million jobs this year. Asked Wednesday about the estimate, Bush distanced himself from the figure. Bush told reporters: “I think the economy is growing, and I think it’s going to get stronger.” Since Bush has taken office, 2.3 million jobs have been eliminated. Meanwhile the Treasury Department announced Wednesday that the national debt had topped $7 trillion for the first time ever.
