Survivors, rescue workers and family members affected by the 9/11 attacks in New York joined Murrah Building survivors on Wednesday on the campus of Oklahoma Christian University for a tree-planting ceremony and dedication of a memorial plaque.

Members of 4/19 Outreach, a nonprofit organization of survivors, family members and rescue workers, donated a seedling from the Survivor Tree at the Oklahoma City National Memorial and a piece of granite salvaged from the ruins of the Murrah Building to the students, faculty and alumni of Oklahoma Christian for their support and encouragement since the April 19, 1995, bombing.

Survivors and rescue workers from the 9/11 attacks drove from New York City with a cutting from the tree that survived the Sept. 11, 2001, attacks on the World Trade Center and a cross cut from the steel of the fallen north tower.

In a show of solidarity between the two cities, the trees were planted alongside each other as a symbol of hope and resilience.
