To which scandal was Kenneth Roy Feinberg retained to assist that started on 18 September 2015?
Volkswagen emissions scandal The Volkswagen emissions scandal (also called "emissionsgate" or "dieselgate") started on 18 September 2015, when the United States Environmental Protection Agency (EPA) issued a notice of violation of the Clean Air Act to German automaker Volkswagen Group. The agency had found that Volkswagen had intentionally programmed turbocharged direct injection (TDI) diesel engines to activate some emissions controls only during laboratory emissions testing. The programming caused the vehicles' NO output to meet US standards during regulatory testing but emit up to 40 times more NO in real-world driving. Volkswagen deployed this programming in about eleven million cars worldwide, and 500,000 in the United States, during model years 2009 through 2015.
UBS tax evasion controversy The Swiss bank UBS AG became embroiled in controversy starting in 2008 when the U.S. Federal Bureau of Investigation (FBI) made a formal request to travel to Switzerland to probe a multi-billion-dollar tax evasion case involving the bank. The investigation had, in part, been prompted by disclosures made by Bradley Birkenfeld, a former UBS banker in Switzerland, who testified to the U.S. Department of Justice (DOJ), the U.S. Securities and Exchange Commission (SEC), and the U.S. Internal Revenue Service (IRS) that UBS had directed its North American sales force to recruit U.S. taxpayers by offering them access to offshore financial vehicles to hide their assets and evade taxes.
