DETROIT -- A day after filing for bankruptcy protection, automaker General Motors Corp. says its U.S. sales in May fell 30 percent from a year ago but were 11 percent better than in April, according to The Associated Press.

GM said Tuesday that improved consumer confidence levels last month helped buyers shrug off concerns about the automaker's impending Chapter 11 filing.

GM says it sold 191,875 cars and light trucks in May.

GM's Pontiac, Hummer, Saturn and Saab brands were the company's worst performers. GM has said it plans to get rid of those brands as part of its restructuring.
