Okay, I checked out that link. All that that shows is that he used an organization credit card to make purchases that should not be charged to the organization. Unless their accounting department blindly approves and pays these CC statements (which I doubt), this is not an issue. He would have to file expense reports and receive reimbursements from the organization. Unless they can produce the expense report where he charged these to the organization and shows that their accounting department reimbursed him, this is not a story.
It is his name on that CC and he has to pay the bill. Anyone with a company CC knows that. And lots of people put personal charges on their company CC for the miles/hotel points/etc… These charges don’t get reimbursed by the company or organization.
