The Trump administration on Tuesday released more than 30,000 pages of previously classified or censored documents relating to the assassination of former President John F. Kennedy, providing insight into some of the Central Intelligence Agency’s most sensitive operations over decades.

Newly released documents related to President John F. Kennedy’s assassination in 1963 are giving curious readers more details Wednesday into Cold War-era covert U.S. operations in other nations but didn’t initially lend credence to long-circulating conspiracy theories about who killed JFK.

So far, nothing in the documents has changed the long-held findings that Lee Harvey Oswald acted alone in assassinating Kennedy on Nov. 22, 1963.
