The Koso affair was a bribery scandal involving Isidor Koso, the head of the prime minister's office of the Slovak State. An illegal Jewish organization called the Working Group had been bribing Koso's wife, à ½ofia Kosova, by paying her son's tuition at a private school in Switzerland. Kosova was arrested at the Swiss border in late October 1943 with 5,000 Swiss francs from the Working Group and a letter from Fleischmann to Saly Mayer, the JDC representative in Switzerland, asking him for another 45,000 Swiss francs. Fleischmann and several other ÃÂà ½ employees were arrested. Extremists in the Slovak government attacked those seen as soft on the Jews, and Koso was dismissed.
