David C. Williams (Inspector General)
|David C. Williams|
|Title||Inspector General for the U.S. Postal Service|
David C. Williams is the Inspector General (IG) for the U.S. Postal Service, in the United States Postal Service Office of Inspector General. 
After Securities and Exchange Commission (SEC) Assistant Inspector General David P. Weber alleged improper conduct by SEC Inspector General David Kotz in the investigation of the Bernie Madoff Ponzi scheme, Williams was brought in to conduct an independent, outside review of Kotz's alleged improper conduct in 2012. The Williams Report questioned Kotz’s work on the Madoff investigation, because Kotz was a "very good friend" with Markopolos. Although investigators were not able to determine when Kotz and Markopolos became friends, the Report concluded that it would have violated U.S. ethics rules if their relationship began before or during Kotz’s investigation of Madoff.
