Friends, family and colleagues gathered to pay tribute to Massachusetts Sen. Edward Kennedy on Friday evening after tens of thousands had filed past the Democratic legend's casket throughout the day.

The wake was held at the John F. Kennedy Presidential Library in suburban Boston, where an estimated 45,000 people had filed past the senator's flag-draped casket by Friday evening.

The senator's funeral is scheduled for Saturday at Boston's Our Lady of Perpetual Help Basilica in Boston's Mission Hill section, with at least 40 of Kennedy's fellow senators and former presidents Jimmy Carter, Bill Clinton and George W. Bush slated to attend.
