New York Magazine:
Following Trump’s short and dire speech, Bush departed the scene and never offered public comment on the ceremony.
But, according to three people who were present, Bush gave a brief assessment of Trump’s inaugural after leaving the dais: “That was some weird shit.” All three heard him say it.
A spokesman for Bush declined to comment.
"Declined to comment" is political speak for "Yep."
I still hate him of course, but that is still a pretty accurate summation.
