des moines, iowa. rand paul from kentucky to washington dc, thank you. >> federal authority is wrapping up their investigation into the deadly warehouse fire that killed 36 people in california. fire officials admitting they never inspected the ship as the building was no despite police and city officials receiving several complaints. national correspondent william lodging us with more on this continuing investigation. >> building inspectors dropped the ball by never thwarting those complaints to the fire department especially the fire department is not even required to inspect commercial buildings unless there is a change in use. the landlord never told the city she converted the warehouse to an illegal apartment building the city never inspected. ironically there was a fire station 500 feet away.
