Hoge has publicly denied that any of this was due to direct or indirect pressure from Kissinger, Rogers, or their associates. Maxwell's paper "The Case of the Missing Letter..." lays out extensive evidence to that it was, indeed, due to such pressure. He cites Peter G. Peterson, chairman of the Council on Foreign Relations, as confirming in an interview for "Chronicle of Higher Education" that he communicated Kissinger's anger to Hoge. Further pressure may have been put by Maurice ("Hank") Greenberg, vice chairman emeritus of the Council's board. Maxwell sent emails in December 2004 mentioning pressure from Greenberg; this was before he was aware of Hoge's intent to give Rogers the last word. 2004, 11-12 Peterson and Greenberg were both major donors to the Council; between them they were directly or indirectly responsible for $34 million in donations. Both had helped endow Hoge's chair. 2004, 16
