At the end of the second bruising day of testimony on General Motors’ ignition-switch recall, Mary T. Barra was in no mood for more questions.
As soon as she was excused from a Senate subcommittee hearing Wednesday, the GM chief executive was hustled out the door and into an elevator, surrounded by a cadre of company officials.
It was a hasty retreat from what has become a searing crisis for Barra and a management team that had hoped the congressional hearings would buy the company time to start its recall of 2.6 million small cars, and complete an internal investigation of why it failed to fix a deadly safety defect for more than a decade.
