More telling was a communique sent on 7 November 1944 by the OSS's Secret Intelligence Branch in Bari, Italy, which apparently acknowledged that Wallenberg was acting as an unofficial liaison between the OSS and the Hungarian Independence Movement (MFM), an underground anti-Nazi resistance organization. The OSS message notes Wallenberg's contacts with Geza Soos, a high-ranking MFM leader and further explains that Soos "may only be contacted" through the Swedish legation in Budapest, which was Wallenberg's workplace and also served as the operational center for his attempts to aid the Hungarian Jews. The same message's assertion that Wallenberg "will know if he (Soos) is not in Budapest" is also curious, in that by November 1944 Soos was in hiding and knowledge of his whereabouts would only have been available to individuals closely involved with the MFM. This conclusion is given further weight by additional evidence suggesting that communications from the MFM to US intelligence were transmitted first to Stockholm and then relayed to Washington via Iver C. Olsen, the American OSS operative who initially recruited Wallenberg to go to Budapest in June 1944.
