Was he maybe talking about the metro bombing in Russia?
Of course not:
Mr. Trump described the chemical attack in Syria as a horrible thing and a disgrace.
I think its an affront to humanity, he said, adding it was inconceivable that somebody could do that, those kids were so beautiful, to look at those, the scenes of those beautiful children being carried out.
Asked about what it meant for Russias role in terms of Syria, Mr. Trump said, I think its a very sad day for Russia because theyre aligned, and in this case, all information points to Syria that they did this. Why they did this, who knows? Thats a level first of all they werent supposed to have this.
