At the end of May 1944, George Mantello received and immediately publicized two important reports given to him by Romanian diplomat Florian Manilou who just returned from a fact finding trip to Romania and Budapest at Mantello's request. Manilou received the material from Moshe Krausz in Budapest, who worked with Carl Lutz to rescue Jews. One of the reports was probably Rabbi Chaim Michael Dov Weissmandl's five-page abridged version of the 33-page Auschwitz Protocols: both the Vrba–Wetzler report and Rosin-Mordowicz report. The reports described in detail the operations of the Auschwitz-Birkenau extermination camp. The second was a 6-page Hungarian report that detailed the ghettoization and deportation of 435,000 Hungarian Jews, as updated to 19 June 1944, by towns, to Auschwitz.
