I see. So, he said something nice to one lady. Good. At least he doesn't seem to make a hard policy of offending these widows and bereaved parents. 

Not clear how this excuses his horrid mangling of this with the other lady.  He didn't even remember the guy's name. 

He says he calls them all, but he's contacted less than half of them.

Obama wrote, hand-wrote, personal letters to EVERY family of a fallen service member during his term in office. He had his staff research the details so he could personalize the letters. He called dozens fo those families. he honored their sacrifices in his speeches and in his actions. Even Bush, inarticulate and bumbling as he was, managed to send out letters to all of the families of the 4000 plus who died for his misbegotten wars during his term.

Trump has had the chance, with 20 dead service members to demonstrate some grace, and has already failed on more than half of them.
