Callahan has been compared to Walter Duranty, the British journalist who won a Pulitzer Prize in 1932 for a set of stories written in 1931 on the Soviet Union.
Prof. Mark von Hagen was also commissioned by The New York Times to write an independent assessment of New York Times correspondent Walter Duranty and his reporting on the Soviet Union after the newspaper received a letter from the Pulitzer Prize Board regarding allegations of Duranty's cover up of communist genocide.
In 2003, in response to an international campaign launched by the Ukrainian Canadian Civil Liberties Association, the Pulitzer Board began a renewed inquiry and the Times hired Mark von Hagen, professor of Russian history at Columbia University, to review Duranty's work.
