Did anybody read the article? These "consultants" are a law firm. A big time, big money, white shoe, corporate law firm. They specialize in things like bankruptcy, corporate litigation, mergers and acquisitions and patents. So, what exactly are they "consulting" about. Citadel might well hire this firm. They are bankruptcy lawyers, after all.
The rather vague announcement was made by an NPR board chairman Dave Edwards (probably no relation to Bob), who represents WUWM (University of Wisconsin - Milwaukee). He avoids saying what this firm of some 1300 high priced lawyers is going to consult about (in their never ending quest to run up billable hours).
NPR, like a lot of public sector types, seems to operate on the principle of: When in doubt, hire a consultant.
NPR also has a record of hiring on-air talent with a "day job" some place else. Exhibit A is Cokie Roberts (who used to work full-time for NPR but now really works for ABC).
