DETROIT (WWJ) – General Motors CEO Mary Barra will return to Capitol Hill next week, to face more questioning from a House Subcommittee.

Barra will be joined by Anton Valukas, who lead the company’s internal investigation. The June 18 hearing will be held by the House Subcommittee on Oversight and Investigation, the same panel Barra appeared before in April.

“Earlier this year, Ms. Barra testified that she would not be able to answer certain questions until the company’s internal investigation was complete. Next week we will have the chance to get those answers and compare the company’s findings to our own,” said a statement attributed to full committee Chairman Fred Upton (R-MI) and Oversight and Investigations Subcommittee Chairman Tim Murphy (R-PA). “Mr. Valukas’ exhaustive report revealed disturbing truths about GM’s systemic and cultural failures that allowed this problem to go undiagnosed for over a decade, but many questions remain unanswered about the recalls and resulting changes within the company.”

The statement said Barra and Valukas will be the only witnesses in the 10 AM hearing.

“This testimony by Barra and Valukas is a critical step in our ongoing investigation to uncover the facts as we determine what went wrong and what we can do to prevent future tragedies.”

The Senate committee that questioned Barra in April is also expected to call her back for another session. Scheduling issues could cause that hearing to be pushed back into July.

Many of those questioning Barra expressed frustration that there were many questions that she declined to answer pending the release of the internal investigation. When those results were released, Barra told reporters that she was ready to return to Washington and answer more questions.

“I have said that I am willing to come back after the report is complete,” said Barra at a June 5 news conference. “Mr. Valukas has indicated if there are questions they want him to answer, he will make himself available.”
