I’ve seen two where they had physical contact. In one they’re walking by a high wall, and it just looks like the woman is supporting Hillary as they walk - I think this is after she fell ill and began to leave the gathering. Both shown here:
The first picture is from this video, at around 1:10:

I don’t think there’s any doubt that she was very sick; but I feel, as others do, that this ‘attack’ seems to have been something they’d seen before. They didn’t seem to be acting alarmed.
From what I’ve seen, and others’ comments, it certainly appears that her team/attendants/SS people were not unduly alarmed, and seemed to have dealt with this before.
Seizures/fits/fainting spells/falls/or whatever she has, seem to be not uncommon events.
