The mayor of Pittsburgh was just on CNN. He said that he asked that Trump not visit yet because they want the resources of the city available for the funerals they have starting tomorrow and not on a presidential visit.— lisastark35 (@lisastark351) October 30, 2018
Guess where Trump is going tomorrow?
He's still planning to go to Pittsburgh today.
The mayor explained that he wasn't asking Trump to eschew visiting. A presidential visit requires an enormous commitment of local resources, and they need those resources to protect mourners and the public during the funerals. Evidently, Trump doesn't give a shit.
Otherwise, national leaders of both parties have indicated that they will not be there.
