Yesterday the government was supposed to declassify its final files on the assassination of President John F. Kennedy. That was the deadline set by the JFK Records Act of 1992, but there was an escape hatch: The president had the power to withhold some of the documents on national security grounds. After much vacillating, Donald Trump decided at the last minute to keep some files classified.

A day later, he's still vacillating. The president is "unhappy" about what happened, according to CNN:

President Donald Trump wanted more of the documents related to President John F. Kennedy's assassination released. But when the final requests from government agencies hit his desk on Thursday, there wasn't enough time to go through the hundreds of records the agencies wanted to keep secret, two US officials said. As the deadline ticked away, Trump was confronted with a choice: release all of the 3,100 records without any redactions, or accept the redactions of intelligence and law enforcement agencies and release 2,800 of those documents. Trump agreed to the second option, while also requiring agencies to conduct a secondary review of the information they believed should be redacted within 180 days. But Trump was still miffed by his decision. "He was unhappy with the level of redactions," a White House official said, adding that Trump believed the agencies were "not meeting the spirit of the law."

If this is actually true, it should put to rest any Trumpian fears that the "deep state" is trying to depose him. What intelligence agency would want to get rid of a president so easily manipulated?

You don't need to buy any of the conspiracy theories about John F. Kennedy's death to see that this is a historically significant event that still has several open questions around it, especially with regard to Lee Harvey Oswald's trip to Mexico City shortly before the shooting. And you don't need to be personally interested in the topic to be appalled that the feds are still suppressing information about an incident that took place more than half a century ago. (No, I don't buy the halfhearted excuse that the withheld files may include relatively recent documents added to the stockpile in the 1990s. Even if you think those should still be classified, they aren't all that's still classified. For example: Jefferson Morley, author of a new biography of former CIA counterintelligence chief James Jesus Angleton, notes that Angleton's secret Senate testimony from 1975 is among the missing material.)

The deadline for the remaining documents to be reviewed is April 26, 2018. Maybe we'll see more material after that, but I'm not optimistic. If the agencies involved can drag their feet for this long, they can drag them for another six months. In the disappointed words of Gerald Posner, one of the better-known advocates of the lone-assassin theory: "They have only had 25 years to get ready."
