Melania, President Trump and a modern history of presidential hand holding
Melania Trump is making headlines over her apparent refusal to hold the president's hand.
Example one happened Monday, when she and President Trump were walking down the tarmac after landing in Israel. She appears to swat his hand away.
Example two took place Tuesday, when the pair were disembarking from their plane in Rome. The president appears to reach for his wife's hand, but Melania quickly moves it away, brushing hair out of her face.
Why does it seem to matter? Maybe because we haven't seen such a stir over a physical gesture before.
