Walter Duranty comes immediately to mind.

In a New York Times article dated 23 August 1933, Duranty wrote, "Any report of a famine in Russia is today an exaggeration or malignant propaganda. The food shortage, however, which has affected the whole population in the last year and particularly in the grain-producing provinces--the Ukraine, North Caucasus, the Lower Volga--has, however, caused heavy loss of life." Duranty concluded "it is conservative to suppose" that, in certain provinces with a total population of over 40 million, mortality had "at least trebled." [8]
On March 31, 1933, Walter Duranty denounced the famine stories and Gareth Jones in The New York Times. In the piece, he described the situation under the title "Russians Hungry, But Not Starving" as follows: "In the middle of the diplomatic duel between Great Britain and the Soviet Union over the accused British engineers, there appears from a British source a big scare story in the American press about famine in the Soviet Union, with 'thousands already dead and millions menaced by death from starvation." Malcolm Muggeridge, a correspondent for The Manchester Guardian, called Duranty a "liar".
