O’Reilly gave her the talking points. As he told the incredulous Beck: Jones was a smallfry, not worthy of my radar screen.
But seriously, I suspect BOR is just putting on a show for FNC viewers by pooh-poohing Beck's work on Van Jones as an exercise in tongue-in-cheek macho rivalry in order to ramp up both men's ratings.
That's usually how TV works: they're always looking for a 'narrative' to hook more viewers. But since I don't watch either show, I couldn't say for sure. ;-)
