You still haven't quite clarified what you're looking for. One of the most famous German speakers in USA is Arnold Schwarzenegger - Admittedly he's Austrian, but still. Of all the native German speakers I know, I dont know anyone else that has kept such a thick accent. Do a search on youtube for him - he's the Govenor of California (which is always amuzing to hear him say, or try to say California) There's got to be speaches available if all you're looking for is the accent and what it sounds like in English.
Here's a very quick link that has some of his speeches and news coverage: http://gov.ca.gov/
*Edit* Sorry, I just re-read what you were looking for. I got confused with the wording.
Here's something better though: http://www.youtube.com/watch?v=S2l_wblug3U&feature=related
