I originally thought there might be. A google (note to self..get away from Google) search resulted in many links to a Rafah Refugee camp. Then I checked maps...no Rafah. Edwan is a common Palestinian name or so it seems. Monir and Hasam Edwan (I think there is an Osama as well, will check) COULD be American nationals (sure). I don't know how we can be sure of that. If I can find the FEC form filed (I'm working off the downloaded database) it may give more information.
Finding the forms on the FEC site has been more of a problem than searching the database. Gotta love that transparency in campaign donations! Thank you McCain-Feingold!
