Summary  
The document contains a series of letters and internal communications related to Sergiyi Czornonoh’s claims about providing information on Lee Harvey Oswald to U.S. officials in Bulgaria during August 1963. Czornonoh asserts he met with Mrs. Besera Asenova, the girlfriend of a Russian consul, who informed him that Oswald intended to assassinate President John F. Kennedy. He relayed this information to American Vice Consul Thomas Blackshear in Sofia, Bulgaria, and later provided details to U.S. officials in Washington, D.C., including claims about Oswald possessing a weapon. The Director of the State Department allegedly warned Czornonoh that revealing such information could result in expulsion or medical treatment involving anesthesia gas. Richard A. Sprague, Chief Counsel of the House Select Committee on Assassinations (HSCA), is noted to have reviewed the document and referenced an attached letter from Czornonoh dated 04 December 1976. The text also includes unrelated claims about harassment by FBI agents and issues related to human rights in Sacramento, California, with references to legal correspondence and passport number 0027000.
