This article largely centered around a letter sent from the Pittsburgh affiliate of Bend the Arc: A Jewish Partnership for Justice that criticizes Trump for the harm he has indirectly caused to minorities, people of color and certain religious groups through his dissemination of lies and conspiracy theory that often permeate the mainstream. It tells Trump he is not welcome in Pittsburgh until he denounces white nationalism which has caused a series of hate crimes since his taking office.
The article also detail some of the details of the shooting itself going into the response from the president and the backlash he received for tweeting about the World Series shortly after the shooting.
I think this article works because they use great sources to talk about a topic that is highly news worthy. It talks to members of the Jewish community and some of the people who wrote the letter to add insight to the thinking of the people who penned this letter.
It also has links to some of the presidents other response to tragedy such as the riots in Charlottesville to allow reader to quickly get up to speed.
