The family has announced the passing of John S Macain, The Senator from Arizona and most notably an ardent anti Trump opponent. He was one of the few public figures that Trump was afraid of.
Trump [I cannot dignify him with title of President, as have a high respect for the Office of President] commented on Macain being a hero, he stated that Mcain wasn't a hero, because he was captured and trump liked men who weren't captured.
It's been reported that the family has uninvited Trump to the funeral.
John Macain was a true American patriot, perhaps that's why Trump disliked him.
