In February 1949, the Finnish Communist Party (Suomen Kommunistnen Puolue, SKP) created a six-page memo on Mormon missionaries' activities . Among other charges, it alleged that the Mormon Church was "the warring USA's secret fifth column." The party gave the memo to the press of the Communist Finnish People's Democrative League (Suomen Kansan Demokraatinen Litto, SKDL); thereafter, parts appeared in some leftist newspapers. For example, Hämeen Yhteistyö claimed explicitly that the Mormon missionaries ("young American officers, mainly trained in the Air Force") were part of a CIA operation to build a network on both sides of the Iron Curtain, for example by allegedly trying to make contact with Finnish army officers.
