Former President Clinton will speak at the Oklahoma City National Memorial & Museum on Sunday to remember the scores of people killed and injured by a bomb blast at a federal building.
Clinton was president when one of the deadliest domestic terrorist attacks in U.S. history was carried out. The bomb was built and detonated in front of the Alfred P. Murrah Federal Building by Timothy McVeigh and Terry Nichols on April 19, 1995.
Clinton's comments will be part of the 20th Anniversary Remembrance Ceremony at the museum and memorial in Oklahoma City.
The number of people who died in the blast is still unclear. The tally is generally 168, but one body part that was never identified as from any other victim means the tally may be 169.
The ceremony is to observe 168 moments of silence at 9:02 a.m., the time of the blast. It will also kick off a campaign that asks residents to commit to one act of "service, honor and kindness" during the month of April in remembrance of the attack.
People will have a moment to pin someone as a demonstration of their commitment to upholding what has become known as the "Oklahoma Standard" of caring and generosity.
The museum recently completed a $10-million renovation to better tell the story of the events on that day that changed the city and the nation.
The memorial at the same site is best known for the Field of Empty Chairs, one for each person who died. There's also a Survivors' Wall that was made with panels of granite saved from the Murrah Building.
