Mr. Dulles. Were there other cases, other than the Petrulli and the Oswald case, where Americans attempted to or did renounce their citizenship while you were in Moscow in this period?
Mr. Snyder. No, sir.
Senator Cooper. To whom were you directly responsible in the Embassy?
Mr. Snyder. My immediate superior was Mr. Freers, Edward Freers, who was the Deputy Chief of Mission.
Senator Cooper. Was he informed about this case?
Mr. Snyder. Yes, sir.
Senator Cooper. Who was the American ambassador at that time?
Mr. Snyder. Ambassador Thompson.
Senator Cooper. Did he know about it?
Mr. Snyder. I presume he did. Ambassador Thompson knew everything that went on in his shop. If through no other means, both the Ambassador and the DCM, the Deputy Chief of Mission, read the correspondence coming in and out, and this is their basic line of information.
