Fox’s Chris Wallace commented on the discernibly tense moment when President Donald Trump and first lady Melania joined the other former Presidents and first ladies.

“I have to say I was struck when President Trump and Melania Trump came to the front row that it was as if a chill had descended on that front row,” Wallace said on Fox News.

Trump sat on the end of the row next to Melania, who had President Barack Obama on her other side. Trump and Hillary Clinton did not acknowledge each other.
