I've never watch more than a few seconds of the apprentice; I couldn't  stand to watch such a narcissist. I do however watch Morning Joe almost every weekday morning. It starts at 6 am with a panel that bashes Trump. It doesn't matter the topic it always turns into a hate fest. 

Joe talks over Mika so much that she has learned to communicate very effectively through facial expressions. Her and Joe are in the same shot often, Joe speaks and Mika does a face that communicates her feelings. When she is allowed to speak, she goes after Trump viciously from his mental health to his fake time covers. The rest of the panel monitor Trump's tweets in real time hoping for new ammunition for their assault. 

The past episodes are online Mika cannot deny her behavior all she can do is claim to have played Trump for his expected response. It was only a question of time until Trump attacked back. He hit minutes before Mika and Joe's vacation when they were most vulnerable.  Not spontaneous at all.
