What Trump reportedly said to the grief-stricken widow of Sgt. La David Johnson, who gave his life for his country, is not some kind of minor miscue or media-fueled distraction. It speaks to the core issue of Trump's character and demonstrates, as clearly as any incident to date, his unfitness for the office he holds -- and dishonors.

Trump is a weak, narcissistic man in a job that requires strength and empathy. I'm not sure that empathy is a concept he even understands. He acts as if he believes that feeling someone else's pain is strictly for losers, not winners.

None of this is a surprise. We learned a lot about Trump during the campaign when he attacked the Khan family, who lost a son in Iraq, for having the temerity to attack him politically. We have a president who believes that making the ultimate sacrifice for the nation is less important than supporting or opposing Trump.
