Looked for Schroder in Dept. of State FOIA logs. 21 hits, including this document originally from 8/13/2013:

UNCLASSIFIED U.S. Department of State Case No. F-2015-11790 Doc No. C05884762 Date: 02/29/2016

Which led me to search for NSA/German cooperation.

Which led to these archived pages from Der Speigel re: Snowden, the NSA and the BND (Germany’s equivalent to the NSA) The page I originally landed on did not contain leaked document links. However, the pages had been archived 4 years ago - I opened just a couple of links to Snowden documents, but they appear to be working.

Der Speigel article is a very interesting read, Anons.
