Washington where the new CEO of general motors is facing more tough questions this morning on capitol hill. ABC's Rebecca Jarvis is live in Washington with the latest. Good morning, Rebecca. Reporter: Robin, good morning. We're expecting an emotional day of testimony ahead with gm's CEO Mary barra back in the hot seat with tough new questions including whether senior management had no idea about those ignition problems for over a decade, who did? They've come to the capitol in search of answers. The voice of our daughters who can't speak for themselves today. Reporter: Jane rimer remembering her 18-year-old daughter Natasha killed with Amy Lynn Rademaker when this failed in 2006. Do you swear that the testimony you're about to give is the truth, the whole truth and nothing but the truth? I do. Reporter: Mary barra, the N newly appointed CEO and gm veteran back in the hot seat today for round two of grilling by congressional leaders about why gm decided to the to fix the ignition problem linked to at least 13 deaths for over a decade. It's not acceptable to have a cost put on a safety issue. You're telling us that general motors has changed its position how it handles costs and safety issues? I think we in the past had more of a cost culture and we are going to a customer culture that focuses on safety and quality. Reporter: Gm has now recalled 2.6 million cars with those faulty ignitions. You've been with the company for over 30 years yet you claimed never once did this cross your desk in the last decade. What do you say to the families and how do you explain to them. I was never a part of that process on this issue. Reporter: But this morning, the families who lost their loved ones are looking for more hoping today's testimony answers their questions. There's no amount of money that can replace my daughter. But I do want justice to come out of this. Reporter: One thing this he'll be listening to carefully today are questions about a victims' fund. Yesterday Mary barra said in 30 to 60 days gm will make a decision about how to take care of the victims of those family members.
