Lou Dobbs headed to Fox News ... for an interview with Bill O'Reilly

Lou Dobbs knows the world is watching him closely now for clues that might explain his sudden resignation from CNN. So it's probably safe to read some meaning into the choice of the anchorman's venue for his first big post-CNN interview: He's going on Fox News.

The network is set to announce that Dobbs will be a guest on Monday night's edition of Bill O'Reilly's show, DailyFinance has learned. Warm feelings between the two men goes back to last summer, when O'Reilly publicly defended Dobbs against critics who wanted him fired for repeatedly showcasting the claims of "birthers" who allege President Obama wasn't born in the U.S. Dobbs offered to be interviewed on The O'Reilly Factor then, but quickly backed out, prompting speculation that CNN had ordered him not to appear on a competing network.
