I think more than anything Megyn is consumed with ratings and she will get them any way she can.
I notice sometimes se goes off on a tangent like this. She is consumed with beating O’Reilly and being number one. Her ratings must be going down. She better be careful because The Donald will give interviews to Hannity and O’Reilly and Greta and will leave her out in the cold. I notice that Hannity as unlimited Trump access. I think Megyn may be last man on the Totem pole and she resents that so she does a hit piece on Trump. Bad strategy.
Even Megyn’s star could lose it’s luster, if she’s not careful. The more she gets like Nancy Grace, the more some may artfully, passively avoid her. I recall Sarah Palin refused to go on Bill O’Reily for a long time, until Megyn convinced her to give Bill another chance. Trump does not need her show at all, and Hannity would love a chance to show her up.
