Back in the 1990’s, congress set 25-year limit on release of secret files related to President Kennedy’s assassination. Both Trump and Biden have both extended the limit based on demands from the CIA.
The files are 60 years old. Most of the people involved are dead. Why keep them secret?
The CIA had a policy of assassination of foreign leaders to protect national security that was only revealed in the mid-1970s. What if the CIA had determined that the president was a threat to national security? Is that a possible explanation for refusal to release the records?
For background, here is the most recent postponement from the Biden Administration:
Accordingly, by the authority vested in me as President by the Constitution and the laws of the United States of America, including section 5(g)(2)(D) of the Act, I hereby certify that all information within records that agencies have proposed for continued postponement under section 5(g)(2)(D) shall be withheld from full public disclosure until December 15, 2022.
Usually, when they do something like that, it’s to protect national secrets of some kind.
For example, records of the Navaho Code Talkers from World War II were classified until the late 1960’s. This was because the Army was still using Code Talkers during the Vietnam War, and declassifying at that point in time could have been disastrous.
Will be interesting to see what they are keeping secret for this to not get unclassified by now.
