Answer by taking a quote from the following article:

Vladimir Tismaneanu (Romanian pronunciation: [vladi'mir tism@'neanu]; born July 4, 1951) is a Romanian and American political scientist, political analyst, sociologist, and professor at the University of Maryland, College Park. A specialist in political systems and comparative politics, he is director of the University of Maryland's Center for the Study of Post-Communist Societies, having served as chairman of the editorial committee (2004-2008) and editor (1998-2004) of the East European Politics and Societies academic review. Over the years, Tismaneanu has been a contributor to several periodicals, including Studia Politica, Journal of Democracy, Sfera Politicii, Revista 22, Evenimentul Zilei, Idei in Dialog and Cotidianul. He has also worked with the international radio stations Radio Free Europe and Deutsche Welle, and authored programs for the Romanian Television Company.

Some who oppose or criticize Tismaneanu's appointment to head the Presidential Commission, his selection of other commission members, or the conclusions in the commission's final report, have drawn attention to several texts he authored in Romania, which they perceive as being Marxist-Leninist in content, and his activities inside the Union of Communist Youth. Among the critics of Tismaneanu's early activities was philosopher Gabriel Liiceanu, who stated that they were incompatible with the moral status required from a leader of the Commission. However, Liiceanu endorsed the incrimination of communist regime and eventually the report itself.  After the presentation of the Final Report and the official condemnation of the communist regime by President Traian Basescu in a joint session of the Romanian Parliament, Liiceanu openly expressed his support for Vladimir Tismaneanu and endorsed the Presidential Commission for the Analysis of the Communist Dictatorship in Romania. In November 2007, Liiceanu's publishing house, Humanitas, published in volume format the Final Report. Furthermore, Liiceanu, in the homage to Tismaneanu, when the latter was granted the award of the Group for Social Dialogue (January 2008), openly retracted his initial statements about Tismaneanu's academic and moral stature: "Vladimir Tismaneanu was the perfect person for completing the task of coordinating the Commission, considering that those who spoke after being exposed to this ideology explained it best. Vladimir Tismaneanu, besides owning such insider knowledge on what is communism at multiple levels, he then had an ideal competence, acquired and validated within the American academic environment, in order to be able to study this subject with both familiarity and distance." Liiceanu concluded: "He is the most qualified intellectual in the world for analyzing Romanian communism. His book Stalinism for All Seasons is the classical study in the field."  Early criticism of Tismaneanu based on allegations of communism was also voiced by writer Sorin Lavric. The author revised his stance soon afterward and, in four separate articles, gave his endorsement to both the Final Report and Vladimir Tismaneanu's later publications.
