WASHINGTON (AP) Germany's top transportation official is pledging to cooperate closely with his American counterparts as the countries investigate Volkswagen's emissions-rigging scandal.

Transport Minister Alexander Dobrindt met in Washington this week with U.S. Transportation Secretary Anthony Foxx and Environmental Protection Agency Administrator Gina McCarthy. Dobrindt said his government will share information gleaned during its review of how the German automaker installed software designed to hide dirty emissions from its "Clean Diesel" cars sold since 2009 during U.S. compliance tests.

Both nations are conducting criminal investigations into VW's trickery, which the company first admitted to U.S. regulators last month. German police and prosecutors raided the company's global headquarters earlier this month seeking material to help clarify who knew about the cheating.

VW potentially faces billions in fines for clean air violations.
