This was reported by RIA Novosti with reference to the corresponding CIA report.
The document says that this person in Australia, two days after the assassination of Kennedy, told American diplomats about the possible involvement of the USSR in the crime.
“This man, while discussing topics of interest to intelligence, raised the possibility that the Soviet government had financed the assassination of President Kennedy,” the report said.
Earlier it was reported that the United States has declassified almost 1.5 thousand previously closed documents related to the investigation into the Kennedy assassination.
It follows from some of the documents that the American special services have been studying theories about the USSR's involvement in the assassination of John F. Kennedy for a long time.
On November 22, 1963, the 35th President of the United States, John F. Kennedy, was shot dead in Dallas in the convertible he rode with his wife Jacqueline and Texas Governor John Connally.
According to the official version, the killer was former Marine Lee Harvey Oswald, who was shot and killed at the police station two days after his arrest.
