The late Senator Edward Kennedy’s FBI file, which was to be released this week, is expected to reveal major secrets about the family's history.

However, the release has been delayed as the file has been placed “under further review” pending a requested by the family.
 
The total document, which is believed to be over 3,000 pages long, has been eagerly anticipated by historians who say it will shine light on some of the more controversial history of the Kennedy dynasty.
 
It is believed the file will give information on issues such as the potential threats to Ted Kennedy’s life after the assassination of his brothers President John F. Kennedy and Senator Robert F. Kennedy.
 
And it is also believed to include previously unreported details about Kennedy’s involvement in the accidental drowning of May Jo Kopechne in 1969 when his car drove off a bridge on Chappaquiddick Island.
 
The Kennedys have successfully stalled the release of the files by raising objections about certain information on privacy grounds.
 
Kenneth Feinberg, a former chief of staff to Ted Kennedy, and now part of the Treasury Department, is representing the family on this issue. There has been no comment from the family about the reason for the delay.
 
FBI spokesman Dennis Argall, said information cannot be excluded from the document simply because it is embarrassing.
 
FBI experts are expect to remove references to individuals still living or anything connected to national security, including details related to Kennedy’s own involved in intelligence matters.
