No, he did not. Robert F. Kennedy suspected organized crime and CIA-backed Cuban exiles might have been complicit in his brother’s death. He did not suspect the Cuban communist leader.
Politico propagated this mistake in Philip Shenon’s recent piece about the CIA’s JFK coverup. “Robert Kennedy’s friends and family acknowledged years later that he never stopped fearing that Castro was behind his brother’s death,” Shenon wrote.
I never heard that so I asked David Talbot, author of Brothers, an investigation of what RFK thought of his brother’s death. He replied via email.
“Phil Shenon continues to recycle the myth — long propagated in CIA circles — that Fidel Castro was behind the JFK assassination. He now adds another piece of disinformation, asserting that Robert Kennedy also fell for this CIA propaganda line. This is completely false. I interviewed over 150 close friends, colleagues and family members of Bobby Kennedy, including Kennedy administration officials and insiders, for my book, “Brothers: The Hidden History of the Kennedy Years.” NONE of them indicated to me that Castro was among Bobby’s leading suspects in the assassination of his brother.”
“Instead, they said that RFK immediately focused on the CIA and its ANTI-Castro operation as the source of the plot against President Kennedy. My sources included close advisors of Bobby Kennedy like Adam Walinsky, Frank Mankiewicz, Ed Guthman, Richard Goodwin — as well as assassination researchers with whom Bobby Kennedy met during his secret search for the truth. I also interviewed the widow and close associates of Walter Sheridan, Bobby Kennedy’s top investigator ever since his days as the chief of the 1950s Senate rackets probe. Who are Shenon’s sources?
“RFK was fully aware of how politically explosive his search for the truth about Dallas was, considering the enormous power wielded by the U.S. security forces that he suspected, and the criminal underworld elements with whom they were aligned. So he was very careful in his public remarks about the Warren Report, which he privately considered a whitewash. It is clear from my research that Bobby Kennedy was biding his time until he could return to the White House, at which point he planned to use the full powers of the executive branch to track down those in Washington who were responsible for murdering his brother.”
