Top Hunter Biden attorney asks to withdraw from tax case over concerns he'll be called as witness

Hunter Biden's top defense attorney in the federal government's tax case against his client has asked to be recused over concerns he'll be called as a witness over the related plea deal that unraveled last month. 

Attorney Chris Clark, who helped negotiate the since-withdrawn agreement, is likely to be a "percipient" witness in proceedings regarding the deal, according s court paper filed Tuesday and review by The New York Post. 

"Based on recent developments, it appears that the negotiation and drafting of the plea agreement and diversion agreement will be contested, and Mr. Clark is a percipient witness to those issues," the motion-to-withdraw stated. "Under the 'witness-advocate' rule, it is inadvisable for Mr. Clark to continue as counsel in this case."

The judge is expected to approve the request.
