Intended to serve as a national mosque for all American Muslims, the Islamic Center was built in a traditional Arabic architectural style, complete with a 160-foot minaret from which prayers were to be announced. A colonnade cloister joined the mosque to two wings containing a library, classrooms, a museum, and administrative offices. In the basement of the mosque was an auditorium built to accommodate several hundred people. The Islamic Center’s first director was Dr. Mahmoud Hoballah.  https://www.history.com/this-day-in-history/cornerstone-laid-at-washingtons-islamic-center http://www.dr-hoballah.com/  I don't know the details of Washington's Islamic Center or of Dr. Hoballah's circle of friends in Washington before and after he became director.  Just pointing out the timing.
