I am surprised people even intervened. There are videos of actors portraying a man and woman in public where the woman is abusing the man. Nobody intervenes to help the man.
The woman cares more about being in the spotlight and being the power behind the throne, our version of Edith Wilson, than the well-being of her husband. I knew she is up to no good when she insists being referred to Dr. Biden despite the fact she is not a MD but has a doctorate in education.
