Clearly a staged photo-op. She probably did this for two minutes max.
Below is her visit to Georgia. Between 7:10 and 7:15 of the video she steps back then waits for instructions to move. It takes about 25 seconds and during that time she is not even really looking at the family anymore. Look at how rehearsed the transition appears to be. Most of the cuts leave this part out. It's the pause like she wants to make sure it's perfect that the cameras are ready.
