GM CEO Mary Barra, chief investigator to testify

Barra will appear June 18 before House Energy and Commerce Committee's oversight panel

WASHINGTON – General Motors CEO Mary Barra will be back in front of Congress next week to be questioned further about how GM allowed a deadly defect in an ignition switch to go undisclosed for more than a decade.

Barra will appear on June 18 before the House Energy and Commerce Committee's oversight panel, a House aide said Wednesday. The aide spoke on condition of anonymity because the hearing hasn't been publicly announced.
 
   She'll be joined by former U.S. Attorney Anton Valukas, who last week issued a report on GM's delayed recall of 2.6 million small cars equipped with the switches.  
 
   Valukas's report blamed the delay on a dysfunctional corporate structure and misconduct or poor decisions by some employees. The ignition switches have been linked to at least 13 deaths.
