I agree with you that POTUS should be staying out of this.
I would like to think he would be smart enough to know that, so am hoping this is some type intentional media deflection.
I would truly hope that POTUS wouldn’t be exchanging barbs like this, if it had the potential to hurt Kellyanne somehow (who must have a terrible home life, as it is). Unless he’s trying to get her to quit.
I’ve decided that Kellyanne has tried to get her wayward husband to shut up, but failed, and has given the president the green light to see if he can make him stop.
