Yeah, 1st is not convincing, reeks of confirmation bias. Watch his vid from the phone, looks like POTUS points at the phone not the shirt.
Interesting that the lady "might" have taken a picture of him, but I'm sure they're curious as to what the hell the Q shirts are about and the breadth of its influence.
2nd tweet is a little more convincing, but we can't see what's on his shirt. Just that POTUS points and nods at someone. Was he nodding about "BEST PRESIDENT EVER?!??!" or a Q shirt?
I don't know, but requires too much speculation for me to find it as a "proof", much like the rest of the Q "proofs".
Glad someone gets it. At this point there are chips on the table. I hope whoever Q is, he understands there are real world effects that could be a detriment to the good fight.
