I can’t use the photo, so I will direct readers to their own link and I will direct you NOT to Jan Brewer’s finger (or her mouth for that matter which looks as if she is screaming at the top of her lungs… though perhaps there was engine noise and she just wanted the President to hear what she had to say), but to the President’s right arm and hand (which you can’t see but which you can sort of figure out where it is from the angle and so on). He has moved in and is either putting his hand or trying to put his hand on her arm (perhaps on her elbow). He is trying to draw her in, reduce the distance between them.
