Our guest is Shahan Mufti's, who's new book, American Caliph, recounts an event that's been lost to history-- the March 9th, 1977 Hanafi Muslim siege in Washington, D.C. That day, three buildings in Washington, D.C. were seized by 12 Hanafi Movement gunmen and were held for two days.

The group took 149 hostages, killed a young radio reporter named Maurice Williams, and shot then-councilman and future Washington D.C. mayor Marion Barry. Mr. Mufti describes the background of the group's leader, Hamas Abdul Khaalis, the blood feud between him and the Nation of Islam, a movie about the prophet Muhammed that fueled the hostage-taking, and the tense negotiations that ultimately ended the siege.
