The Russian documents are expected to draw great attention because

The United States has begun to review Russian documents about the life and death of former President John F. Kennedy and expects to release them once the review is complete, the White House said on Monday. The documents, which Russia gave the United States on Sunday, could be of particular interest because Kennedy’s assassin, Lee Harvey Oswald, lived in the former Soviet Union for several years before he returned to the United States and was arrested for killing the former president on November 22, 1963. Russian President Boris Yeltsin surprised US President Bill Clinton on Sunday when he turned over what was described as the results of an exhaustive search of Russian Government, military and private archives for papers about Kennedy and his assassination.
