President Donald Trump is playing it coy on what people will see from long-secret JFK assassination-era files.

Historians assessing the trove of newly released documents are cautioning people against the idea that they contain any groundbreaking information.

What do the Martin Luther King Jr. files say? Nearly a quarter million pages of records related to the MLK assassination were released by the National Archives on July 21.

The MLK files refer to the newly released FBI and CIA documents related to the 1968 assassination of Dr. King.

More than 230,000 pages of documents related to King’s assassination were published in Monday’s release. According to the National Archives, more files will be released as information is reviewed.
