In accordance with the deadline stipulated by the JFK Assassination Records Collection Act of 1992, the National Archives and Records Administration begins releasing assassination records that had been previously withheld due to personal and national security concerns. In seven batches in 2017 and 2018, approximately 34,000 documents were released online. Some had been previously released in redacted form. By presidential order, the release of certain documents was delayed in the interest of national security. Most recently, on December 15, 2021, approximately 1,500 additional records, mostly related to Lee Harvey Oswald, were released. More records are scheduled to be released in December 2022. According to the National Archives, the majority of the documents still withheld in full are tax records.
