Lois Lerner isn't the only one with a rogue computer. The IRS has lost emails from five more employees involved in congressional investigations concerning biases against conservative groups filing for tax exempt status. It previously said it couldn’t find an undisclosed number of emails from Lerner, the former head of the IRS division that processes tax-exempt applications. Included among the five new employees are two Cincinnati agents who also processed applications for tax-exempt status. The tax agency blames computer crashes for the lost emails.
