Deutche Welle claims itself as reporting for Germany but it's content is filled with stories covering a variety of different nations. There also seems to be an emphasis on the 30 different languages that the website can be translated into, most specifically German.
CNN's about me section is more straight forward and to the point and fails to cover any mission statement but emphasizes that CNN is staffed 24 hours 7 days a week. There is also copyright and reprint rules listed.
Deutche Welle's story design is much like storify with embed twitter links provided throughout the written article. The article style provided a lot of paraphrasing by those who saw Mattis' speech at the NATO HQ.
CNN's article style is much like a traditional article with a smaller picture and formmated text to read like a newspaper. The article provided more direct quotes from Mattis and is broken up into different subsections highlighting various issues that are related to the larger central topic.
