The president’s comments come days after files related to President John F. Kennedy’s death were first published.
President Donald Trump questioned on Sunday whether Lee Harvey Oswald was supported in the assassination of John F. Kennedy.
While talking to Trump in the Air Force, Travis asked, “Do you think Oswald killed JFK personally?”
“I did, and I always felt that, but of course he was saved?” Trump said. “No one could say it, and (the case file) was released,” he added.
Trump described the survey as “somewhat dissatisfied,” adding, “maybe that’s a good thing.”
Kennedy was killed on November 22, 1963 while visiting Dallas. As his convoy passed Dealey Plaza, shots rang out of the book deposit building at a Texas school.
Police arrested Oswald. Oswald said the authorities positioned themselves from the perch of snipers on the sixth floor.
Two days later, nightclub owner Jack Ruby fatally shot Oswald in front of news cameras as Oswald was transported from Dallas Police Headquarters to the county jail.
Ruby was convicted of murder in 1964 and sentenced to death. His belief was later overturned by appeal. He remained in custody awaiting a retrial, but was diagnosed with cancer in 1966. He died in 1967 at Parkland Memorial Hospital.
Director Oliver Stone’s 1991 film, “JFK,” explored several theories about Kennedy’s assassination. It was based on works by former district attorney Jim Garrison, among other things, particularly allegations that the US government coordinated the removal of Kennedy in support of then-President Lyndon B. Johnson.
After taking office, Johnson appointed a committee to investigate the assassination of the president, commonly known as the Warren Commission. They also discovered that Ruby’s murder of Oswald was not part of a wider plot to eliminate Kennedy.
