OKLAHOMA CITY (AP) — Thirty years after the deadliest homegrown attack in U.S. history, former President Bill Clinton returned to Oklahoma City on Saturday to remember the people who were killed and comfort those affected by the bombing.

Clinton was president on April 19, 1995, when a truck bomb exploded, destroying a nine-story federal building in downtown Oklahoma City. He delivered the keynote address at a remembrance ceremony near the Oklahoma City National Memorial Museum.
