On 6 August Joffe was made an alternate member of the Central Committee Secretariat and on 20 August made a member of the editorial board of the Bolshevik newspaper Pravda which was then temporarily called Proletary (Proletarian) for legal reasons. Joffe headed the Bolshevik faction in the Petrograd Duma (city government) in the fall of 1917 and was one of the Duma's delegates to the Democratic Conference between 14 and 22 September.
