OKLAHOMA CITY (AP) _ Politicians and relatives of the Oklahoma City bombing victims pleaded Thursday for donations they said are needed to finish a memorial being built at the site of the blast.

At the beginning of a 168-day campaign to honor everyone killed in the April 19, 1995, bombing, organizers said they need $8.6 million to finish the $29.1 million Oklahoma City National Memorial. T-shirts and bumper stickers were for sale at nearby tables.

``I want all Oklahomans to write a check,'' Gov. Frank Keating said. ``We need to dig deep so we can all learn the lesson of April 19.''

Susan Winchester, a state representative whose sister died in the bombing, is sponsoring a bill that would allow Oklahomans to donate a portion of their tax returns to the memorial.

The memorial will include an interactive learning museum and an institute for the prevention of terrorism.

The first ``Day of Honor'' for bombing victims was dedicated to Federal Highway Administration agent John A. Youngblood, who was blown out of the building and buried to his waist in rubble.

The 168th day will be April 19, 2000, the day the memorial is scheduled to be dedicated. The victim honored that day will be Baylee Almon, the 1-year-old girl who was seen across the world in photographs that showed her body cradled in a firefighter's arms.
