Kennedy was fatally shot on June 5, 1968, at the Ambassador Hotel in Los Angeles moments after giving a speech celebrating his victory in California’s Democratic presidential primary.

His assassin, Sirhan Sirhan, was convicted of first-degree murder and is serving life in prison.

Lawyers for Kennedy’s killer have said for decades that he is unlikely to reoffend or pose a danger to society, and in 2021, a parole board deemed Sirhan suitable for release. But Gov. Gavin Newson rejected the decision in 2022, keeping him in state prison.

In 2023, a different panel denied him release, saying he still lacks insight into what caused him to shoot Kennedy.

Robert F. Kennedy Jr., a son of the New York senator who now serves as health and human services secretary, commended Trump and Gabbard for their “courage” and “dogged efforts” to release the files.

“Lifting the veil on the RFK papers is a necessary step toward restoring trust in American government,” the health secretary said in a statement.
