Here are a few samples of what you can find, in the 2+ minute clip, above, from CNN:
"He’s not one to mend fences too readily... I think he’s doing this because he feels he has to do it and I’m also assuming General Kelly has had a big hand in it..."
"I do know from the Bush family that they are very appreciative and think the White House has just bent over backwards, gone to great lengths, been extraordinarily helpful...That said, I just can’t help but wonder if there was a thought bubble over Donald Trump’s head just know, what he was thinking as he stood there..."
"I have to imagine he was thinking, 'how much longer do I have to stand here?'"
"It was somewhat theatrical, uh, in nature, but it's, I, I can't imagine that this is very comfortable for him, these moments and I think it is going to be fascinating to watch the cathedral on Wednesday and how he interacts with these other presidents and how he sits there during these eulogies..."
This proves, once again, that President Trump is damned if he does, and damned if he doesn't... And, don't forget: ORANGE. MAN. BAD.
