On Wednesday, Sen. Claire McCaskill, D-Mo., accused one GM employee of a cover-up. Ray DeGiorgio, the lead switch engineer on the Cobalt, said in a deposition last year for a lawsuit against GM that he never approved a change to the ignition switch. But McCaskill produced a document from GM’s switch supplier that showed DeGiorgio signed off on a replacement, but with the same part number. Failing to change a part number makes the part harder to track.
Appearing Sunday on ABC’s “This Week,” McCaskill said, “There is no reason to keep the same part number unless you’re trying to hide the fact that you’ve got a defective switch out there that, in fact, ended up killing a number of people on our highways.”
Barra called the failure to change the part number “unacceptable.” She said the company has not yet fired any employees in connection with the recall. But she said if inappropriate decisions were made, GM will take action, including firing those involved.
The Justice Department hasn’t confirmed that it’s investigating General Motors, but a person familiar with the case said the probe is underway.
