Don't reporters either 1) have a corporate credit card to charge expenses on, or 2) get reimbursed for travel expenses? And in either case, don't they have to get travel authorizations signed for by their supervisor? I just find it hard to believe that it took so long for the Times to find out that he did not travel to the places he claimed to be reporting from. You would figure that their first clue would be the lack of expenses from these places.
