WASHINGTON – Democratic Sen. Claire McCaskill of Missouri told General Motors' chief executive Wednesday that the automaker operated for years in a "culture of coverup" that led a GM engineer to lie to conceal an ignition switch defect now blamed for at least 13 deaths.
Presiding over a second day of congressional hearings into lethal failures of GM's Chevrolet Cobalt and other models, McCaskill waved a company document that she said proves engineer Ray DeGiorgio perjured himself last year in a lawsuit filed by survivors of a Georgia nurse killed in a 2010 crash.
The newly disclosed document shows that despite his denials, DeGiorgio approved a new design for the ignition switch in 2006. The change apparently wasn't reported to federal highway safety regulators because the GM part number remained the same, an irregularity that Mary Barra, GM's new CEO, called "unacceptable."
Barra withstood a barrage of questions and accusations from McCaskill and other members of a Senate commerce subcommittee who demanded to know how the automaker could have failed to fix the ignition switch for more than a decade. Problems with the defective part culminated in a series of recalls of more than 2.5 million cars since Feb. 7.
Some senators voiced skepticism about Barra's candor in denying that she knew about the problem until Jan. 31 and in promising that the new GM, the one bailed out by taxpayers in 2009, "will do what's right."
Democratic Sen. Richard Blumenthal, a former Connecticut attorney general and U.S. attorney, called it "likely" that the company will face criminal prosecution.
Republican Sen. Kelly Ayotte of New Hampshire, a lawyer, said the failure to issue a new part number "is not a matter of acceptability. This is criminal deception."
Besides parallel inquiries from House and Senate subcommittees, GM faces an investigation by the National Highway Traffic Safety Administration. McCaskill, in a phone interview, said she also has been informed of a Justice Department inquiry.
