A TVNewser tipster wrote yesterday afternoon: "Bob O'Brien a former CNBC/WSJ on air reporter is on Fox Business Network right now."

O'Brien left CNBC in December after more than four years with the network. He took a job with Barron's as its online stocks columnist.

After a check back in the TVEyes archive, it appears this is the fourth time O'Brien has appeared on FBN. O'Brien is not employed by the network.
