What has Trump got in any relation to this?
People died at the hands of a suicide bomber at a singers show. Some of the audience were as young as 6 years old. It's a tragedy, why are you going deeper than that? The last thing you should worry about is what the singer of the show tweeted. It's her account, her words, her show so frankly you should be thankful she shared that she was sorry.
You can't expect a young girl like that to hold herself together after 19+ people have died and many more injured at her own show
OT: Rest in peace and my thoughts are with those affected.
