Super Bowl Commercial Uses Martin Luther King's Words To Advertise Trucks

A controversial ad that aired during Sunday's Super Bowl game featured the voice of Martin Luther King Jr., over an ad for the company Ram Trucks.

The company used portions of King's 1968 sermon, "Drum Major Instinct," to promote its "Ram Nation" volunteer program.
