The national archives released over 10,000 pages of records in connection with Kennedy’s killing, according to details on its website today.

The move is part of a broader effort by the Trump administration to declassify information about the assassinations of a number of high-profile Americans.

The agency previously published records related to 1963 assassination of then-president John F Kennedy, who was killed several years before the senator, his brother.

“Lifting the veil on the RFK papers is a necessary step towards restoring trust in American government,” US health and human services secretary Robert F Kennedy Jr, the senator’s son, said in a statement.

The health chief has previously said he believes his father was killed by multiple gunmen, an assertion that contradicts official accounts.

The Trump administration has also promised to declassify records related to the assassination of civil rights leader Martin Luther King Jr.

The national archives did not respond to a request for comment on when to expect the King files or whether more files would be released in connection with the killings of the Kennedy brothers.
