Who could have pushed her? I think that when she turned, one of her feet went over the edge and she fell.
Whatever caused the fall and whatever her political stance, I don’t like the way that looked. I don’t like seeing people fall. Don’t find it funny. She may well have hurt herself. Nobody has said anything definite about it as far as I can tell. They may have wanted to cover it up so she doesn’t look like the vulnerable female. Doesn’t take much to pull something out of place, twist an ankle or even break a bone.
Whatever happened to her, it’s clear Cruz wasn’t moved to help.
When you look at it closely, you can see her head just as that man came to her aid, so she wasn’t sprawled on the floor. Just as the video ends her head can be seen as if she is ready to step up on the low platform again.
