Weizmann's personality became an issue but Weizmann had an international profile unlike his colleagues or any other British Zionist. He was President of EZF Executive Council. He was also criticized by Harry Cohen. A London delegate raised a censure motion: that Weizmann refused to condemn the regiment. In August 1917, Weizmann quit both EZF and ZPC which he had founded with his friends. Leon Simon asked Weizmann not to "give up the struggle". At the meeting on 4 September 1917, he faced some fanatical opposition. But letters of support "sobering down" opposition, and a letter from his old friend Ginzberg "a great number of people regard you as something of a symbol of Zionism".
