State-NewsRICHMOND, Va. (AP) _ Virginia has joined a multi-state investigation into Volkswagen’s emissions scandal. Attorney General Mark Herring said Thursday that Virginia is one of 28 states participating in a probe into VW’s use of secret software to thwart diesel smog tests on nearly a half million vehicles in the U.S. Herring said in statement that he will ensure that all Virginia consumers impacted by the company’s actions will receive what they are owed. The Environmental Protection Agency has accused VW of installing a so-called “defeat device” to foil emissions inspections in 482,000 cars sold in the U.S. VW later acknowledged that similar software exists in 11 million diesel cars worldwide.
