For the first time since the Kennedy assassination nearly 62 years ago, the CIA has tacitly admitted that an officer specializing in psychological warfare ran an operation that came into contact with Lee Harvey Oswald before the Dallas killing. Via Axios:

Why it matters: The disclosure Thursday — nestled in a batch of 40 documents concerning officer George Joannides — indicates the CIA lied for decades about his role in the Kennedy case before and after the assassination, according to experts on JFK's slaying.

The linchpin document: A Jan. 17, 1963, CIA memo showing Joannides was directed to have an alias and fake driver's license bearing the name "Howard Gebler."

Until Thursday, the agency had denied that Joannides was known as "Howard," the case officer name for the CIA contact who worked with activists from an anti-communist group opposed to Cuban dictator Fidel Castro called the Cuban Student Directorate.

For decades, the agency also falsely said it had nothing to do with the student group, which was instrumental in having Oswald's pro-Castro stances published soon after the shooting.

The bottom line: "The cover story for Joannides is officially dead," said Jefferson Morley, an author and expert on the assassination. "This is a big deal. The CIA is changing its tune on Lee Harvey Oswald."

Joannides played a central role in deceiving the House Select Committee on Assassinations.

At the time, the CIA appointed Joannides to be its liaison with the committee. But he and the agency hid the fact that he was involved with DRE and therefore the Kennedy case, slow-walked the CIA's production of records, and lied.

The committee's chief counsel, Robert Blakey, testified in 2014 that he asked Joannides about "Howard" and DRE, and that "Joannides assured me that they could find no record of any such officer assigned to DRE, but that he would keep looking," Blakey said.
