Comrade BERIA, L.P.
In accordance with your instruction of 29 September 1944, NKGB USSR continues measures for obtaining more detailed information on the state of work on the [problem of uranium] [handwritten] and its development abroad.
In the period 1942-1943 important data on the start of work in the [USA] [handwritten] on this problem was received from our foreign agent network using the contacts of Comrade Zarubin and Kheifitz in their execution of important tasks in line with the executive committee of the Comintern.
In 1942 one of the leaders of scientific work on [uranium] in the USA, Professor Oppenheimer while being an unlisted (nglastny) member of the apparat of Comrade Browder] [handwritten] informed us about the beginning of work.
On the request of Comrade Kheifitz, confirmed by [Comrade Browder,] [handwritten] he provided cooperation in access to research for several of our tested sources including a relative of [Comrade Browder] [handwritten].
Due to complications of the operational situation in the [USA,] [handwritten] dissolution of the [Comintern] [handwritten] and explanations of Comrades Zarubin and Kheifitz on the Mironov affair it is expedient to immediately sever contacts of leaders and activists of the [American Communist Party] [handwritten] with scientists and specialists engaged in work on [uranium.] [handwritten]
NKGB requests the consent of the leadership [Instancia].
