Attorney General Ken Cuccinelli is hiring an outside law firm to represent the state in a tax lawsuit filed against Virginia by a company in which Cuccinelli has investments. 

The office will make the announcement Friday after reports by The Associated Press and the Washington Post detailing Cuccinelli's interests in Star Scientific Inc., valued at $10,000 to $50,000 and personal gifts totaling about $13,000. It represents Cuccinelli's lone stock investment.  

The company sued Virginia over a disputed $700,000 tax bill in 2011. Cuccinelli's office is defending the state Department of Taxation, despite the appearance of a conflict of interest. The case has sat dormant since the state filed a response to the company's complaint in August 2011.    

Cuccinelli is Virginia's presumptive 2013 Republican gubernatorial nominee.
