A General Motors engineer signed off on a design change for troubled ignition switches even though those changes did not meet company standards, according to documents provided to a U.S. House of Representatives panel. The document appeared to be in conflict with information provided by GM engineer Ray DeGiorgio during 2013 legal proceedings surrounding the company's defective ignition switches that are linked to 13 deaths. http://feeds.reuters.com/~r/Reuters/PoliticsNews/~3/_9cf1e3BSqg/story01.htm http://www.wochit.com
