That's a wonderful resource in those press pool reports, thank you! With that info, I've updated the graphic from yesterday's notables with an important new conclusion: Q 1 was posted while POTUS was still riding in the 2017 motorcade that was just featured in a video shown Saturday on the POTUS_Schedule twitter.
Earlier we'd figured out that the video was taken 29 minutes before Q 1 dropped. Now we know POTUS was still in the motorcade. It departed at 3:12 pm, was filmed at 3:15 pm, Q 1 dropped at 3:44 pm, and POTUS arrived at the White House at 3:59 pm.
