So? Lots of Americans whose German-speaking families came to the US in the 1930s were of Jewish descent, for obvious reasons.
Kissinger's and Albright's families are indeed both Jewish, but Albright herself was raised a Catholic and became an Episcopalian as an adult; she has said her parents didn't tell her they were Jewish until it came out in the media in the mid-1990s. I have no idea whether Kissinger is religious.
Albright has absolutely no foreign accent. Her family left Czechoslovakia for London when she was only 2, and emigrated to the US when she was 9. Her bio lists German among her languages, but it's apparently not as fluent as her French or Russian. Condi Rice, once a student of Albright's, probably also had mainly a reading knowledge of German when she was still in academia.
Kissinger, on the other hand, was already 15 when his family left Germany, and he has a German accent so thick it can be almost impenetrable. (He mumbles as well, especially the older he gets, which doesn't help.)
But both of them are currently retired, out of government. I'm not aware of any active elected politicians who are known for speaking fluent German, though there are probably some who studied it in high school or college, and possibly even some from military or diplomatic families stationed in Germany for a time.http://en.wikipedia.org/wiki/Madeleine_Albrighthttp://en.wikipedia.org/wiki/Henry_Kissinger
