Bentley wrote in her autobiography "Out of Bondage" (1951) that she had been "able through Harry Dexter White to arrange that the United States Treasury Department turn the actual printing plates over to the Russians." In her 1953 testimony before McCarthy's Senate subcommittee, she elaborated, testifying that she was following instructions from NKVD New York "rezident" Iskhak Abdulovich Akhmerov to pass word through Ludwig Ullmann and Nathan Gregory Silvermaster for White to "put the pressure on for the delivery of the plates to Russia."
