Volkswagen execs indicted, accused of lying to U.S., California officials in diesel pollution scandal

Six Volkswagen executives were charged Wednesday with approving the carmaker’s plan to evade U.S. air-pollution laws – and spending more than a year stonewalling investigators from the California Air Resources Board and the U.S. Environmental Protection Agency.

More than 500,000 were sold in the United States.
