One step forward, two steps backward. It has become The Pattern. Trump's Pattern. Well established.
He has a tendency to 'step in it' via his tweeting. He would have done much more toward the cause of being pro-Sanders and anti-Red Hen by simply saying that what they did, drive her and her family out of the restaurant mid-meal, was (or should be) beneath most adults in DC. Sadly and unfortunetly, however, since he has weighed in in this manner, there will be much more examples NOW of the same bigotry against anyone that works for him in any capacity.
Heckuva job, Trumpy!
