US President Barack Obama, his wife Michelle and Bill and Hillary Clinton will visit the grave site of John F Kennedy this week, to mark the 50th anniversary of his assassination.
The Democratic Party champions will lay a wreath close to the eternal flame that marks the resting place of the 35th US president at Arlington National Cemetery outside Washington.
The poignant moment of remembrance will come two days before the November 22 anniversary of Kennedy being gunned down in an open top limousine in Dallas in 1963, in a crime which traumatised the world.
The White House said Obama would also give a speech on Wednesday evening honouring Kennedy's legacy of service at a dinner for awardees of the Presidential Medal of Freedom.
The annual awarding of the medals was initiated by Kennedy, and former president Clinton, former Washington Post editor and Kennedy confidant Ben Bradlee and talk show host Oprah Winfrey are among those getting medals this year.
