US-AUTO-SAFETY-RECALL-GM

Embattled General Motors CEO Mary Barra is back in Washington, DC today, briefing congressional lawmakers on why it took the company ten years to recall cars with defective ignition switches.

According to The Wall Street Journal, the trip coincides with the completion of an internal investigation into what went wrong with GM's recall process, by attorney Anton Valukas. His findings will be presented separately. Once released, though, Barra told lawmakers that she'll be able to be more open and candid in her responses to questioning.

That's a good thing, as Claire McCaskill, the Democratic senator from Missouri, has already said that Barra will be forced to testify again, unnamed sources in meetings on Capitol Hill told The Journal.

Meanwhile, Colorado's Democratic representative, Diana DeGette, who is leading an investigation by the House Energy and Commerce subcommittee, met with Barra. According to The Journal, she said it'd be "a matter of weeks," before Valukas' report was released.

DeGette did speak positively of the meetings, though, saying "there is an effort to improve communication and oversight," at GM.
