The nominal deadline for release of the last remaining records concerning the assassination of President Kennedy under the terms of the JFK Assassination Records Collection Act of 1992 is October 26, 2017.
Agencies have an opportunity to request postponement of release, beyond the deadline, of a few thousand records that are still being withheld, subject to Presidential approval. Officials would not say if any such requests have been forwarded to the White House, but so far none are known to have been approved by President Trump.
In a resolution introduced in the Senate last week, Senators Charles Grassley and Patrick Leahy called for full release of all remaining assassination records.
They urged the President of the United States to “reject any claims for the continued postponement of the full public release of those records.”
