FBI evidence used to convict Timothy McVeigh and Terry Nichols goes on display today at the Oklahoma City bombing memorial.
The display includes everything from fingerprint and tire-tread evidence, to mangled pieces of the truck used in the explosion, and the Glock handgun taken from McVeigh when he was arrested 90 miles from the bombing site.
Museum executive director Kari Watkins says conspiracy theories will always be linked to the bombing, just as they have persisted since the assassination of President John F. Kennedy in 1963.
California congressman Dana Rohrabacher plans to conduct hearings on the bombing November 15. He wants to know if it's possible there were foreign connections to the bombing.
