I think Donald should take a pause....and really ask the question. He should in a sincere way say what we all really want to know, is Hillary ok? She doesn’t seem ok. If the question is out there then someone has got to answer and the question will elicit more photos and questions about her odd behavior.
I think he will get further with asking sincere, than sarcastically. Because it then becomes a serious issue.
My opinion

So Trump can indeed ask questions.
