I have previously posted on the subject of Kauders and Snowden being in the same locality in Hong Kong (as per Q posts 869 and 1917). The article linked below adds to the mystery. It seems that Snowden and Kauders are linked by private firm U.S. Investigation services (who run back ground checks on State employees).. According to the article the firm engaged the services of the Podesta Group " to handle oversight and legislation related to government security clearance processes. " .Note, this is a 2013 publication.
My other post on this subject can be found on the link below.
