They wear dog-tags! This veteran lost both his arms. The feeling of a handshake is lost to him. Trump realized this and, thus, touched his face so he can feel the human connection. This is what I see when I think of Trump's motives. He gave up a billionaire lifestyle so he could be insulted, dragged through the mud, and lied about on a daily basis. All to save the country and people he loves - as did the hero he is touching. God Bless America. In God We Trust.
