A lawyer for Zhenli Ye Gon, the international pharmaceuticals businessman accused of participating in a methamphetamine trafficking conspiracy, has withdrawn from the case more than two years into the litigation.

The lawyer, Martin McMahon of Washington, D.C.’s McMahon & Associates, said in a recent interview that he was planning to withdraw amid a dispute over attorney fees with Ye Gon, who has remained jailed since his arrest in suburban Maryland in July 2007.
