Prosecutors are not backing down from pursuing an assault case against a New York solo practitioner who is accused of resisting two deputy U.S. marshals during an alleged skirmish in federal district court in Washington, D.C.

The U.S. Attorney’s Office for the District of Columbia this month secured a two-count superseding indictment against the lawyer, Ning Ye, who once represented a man in the U.S. District Court for the District of Columbia who was accused in a high-profile international methamphetamine trafficking conspiracy. (The government’s case against the man, Zhenli Ye Gon, collapsed recently under the weight of evidentiary concerns, among other reasons.)
