Justice Department Accused of Superfluous Spending

An audit report of the Justice Department’s costs for conferences over a few years shows unreasonable ostentatious spending. Of course, the department denies certain unnecessary purchases but it doesn’t seem likely that the inspector who conducted the audit would fabricate lists of expensive snacks and trips. Should the Justice Department’s spending be this flexible? Would the government be overreacting if it gave the department stringent spending rules or budgets?
