 People say they split off, but I think it's a little more complicated that Hezbollah Brigades and the Sibal Haq, or League of the Righteous, were two of the prime militias. They were formed by Mahdi Army commanders. The U.S. military called them the Mahdi Army Special Groups, and we talked about them well over a decade ago, John, and they're still here. The Sibal Haq is run by a man named Qais al-Ghazali. He was in U.S. custody.
