Megyn Kelly sat down with the Oklahoma woman who was nearly beheaded in an attack that shocked the nation.

On September 25th, 2014, food plant worker Alton Nolen walked into Vaughan Foods in Moore, Okla., and beheaded one of his coworkers. He was trying to decapitate a second when the plant owner heroically stopped the attack.

Traci Johnson was Nolen’s second victim. She completely avoided the national spotlight after the horrific incident, until now.

Megyn asked Traci about the killer, whether he was motivated by racism or terrorism - an issue still not decided by law enforcement - and what it was like when she realized that this man was trying to cut her head off.

Programming Note: Due to the mass shooting in South Carolina, this interview has been rescheduled. Tune in to "The Kelly File" at 9p ET for further information.
