Eyeing major settlement, US states move quickly in VW case

Forty-five states and D.C. have joined a multistate investigation led by attorneys general, which is determining how VW was able to game emissions tests to hide that its "Clean Diesel" cars emitted smog-causing exhaust up to 40 times dirtier than the law allows. California and Texas are conducting their own investigations for now. At least one county, Harris County in Texas, also is going after Volkswagen with a lawsuit seeking more than $100 million.
