Congress should raise the federal gasoline tax to help fix roads and bridges, Thomas Donohue, president of the U.S. Chamber of Commerce said today, CNNMoney reported. "Twenty years. It's been 20 years since we had an increase in the federal fuel tax. What kind of car were you driving 20 years ago?" Donohue said. The last increase in the federal gas tax was on Oct. 1, 1993 at 18.4 cents a gallon. Last week, former U.S. Department of Transportation Secretary Ray LaHood said Congress should raise the federal gas tax by 10 cents a gallon.
