The National Archives and Records Administration published on Friday another batch of records – 676 to be exact – pertaining to the assassination of John F. Kennedy in 1963.

Originating from a variety of government agencies, the vast majority, 553 documents, come from the Central Intelligence Agency. These were "previously denied in their entirety," NARA said in a press release titled, "Never Before Released JFK Assassination Records Opened to the Public."

NARA said that the records in the public release "have not been reviewed by" the agency. The CIA simply referred the Washington Examiner back to NARA when asked for comment on why the files from the CIA were chosen to be released now.

The rest of the files derive from the Departments of Justice and Defense, the House Select Committee on Assassinations, and the National Archives.

Friday's public release is the third this year. Last week, on Oct. 26, the remaining 3,100 JFK documents were up for release, subject to the President John F. Kennedy Assassination Records Collection Act of 1992, but Trump blocked about 300 of them, while giving concerned agencies six months to review their contents for possible redactions related to "national security, law enforcement, and foreign affairs concerns."

Trump also "ordered that all remaining records governed by section 5 of the JFK Act be released, and thus additional records will be released subject to redactions recommended by the executive offices and agencies," NARA said.

Among the new revelations is a document in which U.S. official described the behavior of Lee Harvey Oswald, the lone gunman responsible for Kennedy's assassination, as "odd" in 1960, three years before the shooting, after examining a dispatch on Oswald over his return to the U.S. from the Soviet Union.

Another 20-page document discussed ties civil rights icon Martin Luther King Jr. had with communist influences and possible extra-marital affairs.

The documents are the first to be released since President Trump pledged in a tweet last Friday to release all of the secret records, leaving out only the names and addresses of any mentioned person who is still alive.

He also said that he is "doing this for reasons of full disclosure, transparency and in order to put any and all conspiracy theories to rest."

A number of conspiracy theories have swirled amid the secrecy in what the government knew about the circumstances of Kennedy's assassination in Dallas. Some, like longtime political operative Roger Stone, have argued, among other things, that Lyndon B. Johnson orchestrated the assassination and the Sen. Ted Cruz's father, Rafael Cruz, was involved.
