Here are a few crumbs I have gathered up regarding the recent "mirrors" we've seen.

Scavino reflection in the desk (sorry don't know how to do those special non twitter links) Kayleigh reflection in the desk (can someone smarter than me provide an archived link?)

This researched article about the Arizona Mirror from GWP (thanks u/7Nick9)

and this mirror comment from Putin (thank you u/not_a_sheep):

Putin countering criticisms in the interview by bringing up the Capitol thing and Ashli Babbitt. Even used the word 'mirror'.

From NBC [1]: "We have a saying: 'Don't be mad at the mirror if you are ugly,'" he said. "It has nothing to do with you personally. But if somebody blames us for something, what I say is, why don't you look at yourselves? You will see yourselves in the mirror, not us."[1] https://www.nbcnews.com/news/world/putin-talks-hacking-navalny-capitol-riot-ahead-biden-summit-n1270640

and another anon noted Trump's upcoming return trip to the border scheduled for June 30, 2021. He last visited the border on Jan 12, 2021, and that was (supposedly) his last official trip as POTUS. https://www.breitbart.com/politics/2021/06/15/donald-trump-announces-visit-to-nations-decimated-southern-border-before-kamala-harris-has-planned-trip-there/

Please add what you've noticed and let's see what we can come up with!
