On July 29, 2021, I submitted the following request for information through the NARA website:

Would you please advise me whether any federal agencies, especially the CIA, have expressed an interest in seeking an extension of time for continued secrecy with respect to the JFK records that are set to be released in October?

On August 10, I received the following email from NARA:

Dear Mr. Jacob Hornberger,

After looking into your request, we are able to confirm that at this time NARA and other federal agencies are in the process of reviewing JFK assassination records in accordance with the requirements of the President John F. Kennedy Assassination Records Collection Act of 1992 and the April 26, 2018, Presidential Memorandum on Certification for Certain Records Related to the Assassination of President John F. Kennedy. Similar to the 2017-2018 release, NARA plans to make the releasable records from the 2021 review available on the National Archives website.  More details will be communicated as updates arrive.
