Among the subjects General Kelly brought up in his speech was how women used to be sacred and they no longer are treated with respect. He brought up Gold Star families and their sacrifice. His family is one since he lost a son. He also said that selfless service to this country is no longer required.
Trump has a reputation of treating women disrespectfully (Access Hollywood tape shows that)
Trump attacked a Gold Star family repeatedly during his campaign
Trump has not served this country in any capacity and he certainly isn't selfless
Whether General Kelly gets away with it without someone calling Trump's attention to it I don't know. It may take awhile for Trump to figure it out. We shall see.
