according to a congressional aide who asked not to be identified because the meetings were private.
Among the lawmakers Barra met with were Sen. Claire McCaskill, D-Missouri, and Dianna DeGette, D-Colorado. Both were highly critical of the chief executive last month when she testified at Senate and House hearings about GM's handling of the ignition switch problem. With victims' families looking on, Barra said she was unable to answer many questions until an internal investigation into the matter was complete.
Frustrated, lawmakers finally elicited a promise from Barra to return to testify when the company's probe was finished.
In late May or early June, she'll have answers. The automaker hired former U.S. Attorney Anton Valukas to investigate why it took so long for GM to recall the small cars. GM has promised an ''unvarnished'' report, and Barra told Congress last month she will take decisive action on its findings.
The company also hired compensation expert Kenneth Feinberg to negotiate settlements with crash victims. Lawyers say they have at least 400 possible cases against GM, and the settlements could cost the company billions.
Last week GM admitted to concealing the ignition switch problems from the National Highway Traffic Safety Administration and agreed to pay a $35 million fine, the maximum the agency can impose.
On Thursday, three senators introduced a bill that would lift the $35 million cap, saying that the current amount is too low to discourage automakers from hiding problems.
