O'REILLY: And finally tonight, the Factor Tip of the Day. Loyalty. Last night after speaking with me here on the Factor, Donald Trump once again tweeted some not nice things about Megyn Kelly. Not good. The debate issue should be buried. It's over. Folks can make up their own minds about it.

Fox News chief Roger Ailes once again stood up for Megyn because Roger's a loyal guy, and as the general here, he protects his troops. Roger Ailes has defended me countless times against unfair assaults by vicious media people. The Kelly/Trump story is relevant to me because I'm friends with both of them. They both bring things to America that are worthy and positive. Ms. Megyn has taken the high road by not responding. Donald Trump should cease, and Roger Ailes is a stand-up guy. Factor Tip of the Day.
