Geraldo Rivera was a guest on The O'Reilly Factor last night on FNC to promote his new book, "His Panic," and while it wasn't exactly Rivera-O'Reilly II, the debate hinged on illegal immigration again. Rivera took on Bill O'Reilly's immigration attacks (although he did compliment the host for being "much more moderate on this issue than flame-throwing conservatives") and the interview got heated towards the end. So, will Rivera guest on CNN's Lou Dobbs? Maybe not, as ICN reported earlier this month, that Rivera got bumped from Nancy Grace more than two weeks in advance for a "scheduling conflict."
