Looking at congress playing games during POTUS speech.
Largest resolitions I could find.
Note that some addy's in far left phone are blurred (@POTUS for example) meaning image is not original, however dates and times and tweets should be diggable (we can figure out what the convo on the left phone was.
Getty removed their original (earliest by date. Perhaps someone can dig around.
Did not check exif info.
Many outlets cropped picture to include only two on the right)
Use this oldest for EXIF

This is yhe highest res. Exif has been heavily reduced BUT left phone text is readable:

Print that phone text out and search for tweets on or about that date, and that's what everyone else was hiding
Happy hunting!
