Transcript for Trump points to 'rogue killers' in journalist's disappearance

We begin with fast-moving developments in the disappearance of Jamal khashoggi. Turkish authorities say he was killed. You remember this surveillance, khashoggi going into the consulate, his fiancee waiting outside. And now, the first Saudi investigators going into the door. Our team on the scene. This is now 13 days since his disappearance. Tonight, president trump says he has talked to the Saudi king, that he denies any knowledge, and the president saying this could be rogue killers. Here's Ian Pannell from the scene tonight. Reporter: A team of Saudi investigators sweeping into their consulate even as the Saudis face accusations that the missing "Washington post" columnist was tortured and murdered inside.
