Conrad Black arrives at the Dirksen Federal courthouse in Chicago May 8, 2007. Black's former business partner, David Radler, who has already pleaded guilty to fraud, has taken the stand as the star witness against the fallen media baron and prosecutors have begun to link the two men as inseparable in running Black's company.
