Ray DeGiorgio, the General Motors engineer who was called out during the GM ignition switch hearing and subsequently suspended, spoke with congressional investigators earlier this month.
The New York Times reports that DeGiorgio talked with investigators for ten hours on May 19th about his involvement in the ignition switch recall. As you might recall, DeGiorgio was the engineer who signed off on a change to the ignition switch in certain GM vehicles. However during testimony in a wrongful death suit, DeGiorgio claimed he didn't remember authorizing any change to the ignition switch.
During his questioning with investigators, DeGiorgio appeared “genuinely upset” according to a house aide.
“He came across as if he was just overburdened and just missed it,” said the aide.
DeGiorgio said that he forgot that he signed off on the change for the ignition switch because it was a part of of a package of changes, and that seven years had passed from the time he signed off to testifying. DeGiorgio also didn't give any information that indicated that GM CEO Mary Barra knew about this problem before she took on her new role earlier this year.
