WASHINGTON (AP) A bipartisan group of lawmakers is seeking documents and a briefing from Volkswagen as part of a congressional investigation into the German automaker's emissions-rigging scandal.

The leadership of the House Energy and Commerce Committee sent a letter to Volkswagen's CEO Tuesday requesting all documents and communications related to compliance with the Clean Air Act and EPA emissions standards. Committee leaders also want documents related to compliance with California's emission standards.

Volkswagen AG has admitted using a piece of engine software to cheat on diesel car emissions tests in the U.S. and abroad.

The energy committee announced last week that it would soon hold hearings on the scandal. Committee leaders said they want the documents by Oct. 13. They requested a briefing from VW by the end of the week.
