The Federal Bureau of Investigation today released over two thousand pages of its files on former U.S. Senator Ted Kennedy, who died last year after a battle with brain cancer.

According to the bureau, the bulk of the material in the file, made public under the Freedom of Information Act, is related to "threats of violence and other extortion claims against Senator Kennedy and other public officials." The files also include information about Kennedy's 1968 car accident at Chappaquiddick Island when Mary Jo Kopechne was killed; information the bureau collected on Kennedy's travels; and material related to the Kennedy family's place in American politics.

Kennedy was interviewed multiple times by Big Think during his final years, speaking on a variety of issues, including globalization, philanthropy,  how he was shaped by his childhood, and his vision of the American legacy.
