Taylor is currently on the stand for cross-examination. Prosecutors told ABC News that Friday will be Taylor's last day on the stand.
Over the course of the two-year long trial, Taylor has grabbed headlines by firing his first attorney and converting to Judaism. United Nations officials decided that for security reasons it would be safer to try Taylor at the International Criminal Court in the Hague rather than in Sierra Leone where the atrocities occurred.
Prosecutors have accused Taylor, who served as Liberia's president from 1997 to 2003, of ordering his subordinates to murder and mutilate civilians, cut off their limbs, use women and girls as sex slaves, abduct adults and children, and force them to perform labor or become fighters to further his economic and political ambitions in the region. Taylor has pleaded not guilty to all charges.
Defense attorney Griffiths has previously blasted the War Crimes Tribunal as "racist," and a tool of American foreign policy.
In October, former lead prosecutor Stephen Rapp told ABC News that illegal diamond money was a major motivation for Taylor's rape of his neighboring Sierra Leone: "It's [Sierra Leone's} rich diamond fields which financed the continued conflict, and according to our evidence, was part of the motivation for Taylor in going in there and carrying out a conflict that ranged across the 1990s with an increased level of atrocity against the civilian population."
