One of the hardest jobs for a president is calling a grieving parent
I would guess, one of the hardest jobs for a president is calling a grieving parent of a solder who has died in service to the country. Different people would react differently to what is said. Words can not replace the loss. It's even hard to know what to say as an ordinary person to someone who is facing a serious loss. I say this not in defense of Trump as I don't like Trump anyway. In someways it's good to see so many people critical of him, but I also realize that death, loss and grieving can be difficult.
