What’s up with the prices at the pump?

Oil prices at the pump fell hard, then began creeping back up -- even though crude oil prices have not rebounded. One reason is an explosion at an ExxonMobil refinery in California that has bumped that state's price by 20 cents a gallon, but if the steelworkers union strike expands the impacts could grow . Meanwhile, the Saudis, who concocted the scheme that saw the dramatic drop in prices, are happy to see the rise in the price at the pump.
