The subcommittee of the House Committee on Oversight and Government Reform wanted to determine if government officials , including from NHTSA , purposely held back information on the Volt fire for political reasons . Both Daniel Akerson , General Motors CEO , and David L. Strickland , NHTSA administrator , denied any wrongdoing .
