"In January 1948, Mikhoels was killed in Minsk by Ministry of State Security agents who staged the murder as a car accident.[7] The members of the Jewish Anti-Fascist Committee were arrested. They were charged with disloyalty, bourgeois nationalism, cosmopolitanism, and planning to establish Jewish autonomy in Crimea to serve US interests."
Also interesting side note from the same article:
The Jewish Anti-Fascist Committee,[a] abbreviated as JAC,[b] was an organization that was created in the Soviet Union during World War II to influence international public opinion and organize political and material support for the Soviet fight against Nazi Germany, particularly from the West. In the US, they were welcomed by a National Reception Committee chaired by Albert Einstein and by B.Z. Goldberg, Sholem Aleichem's son-in-law, and American Jewish Joint Distribution Committee. The visit drew the attention of the American public to the necessity of entering the European war."
