As I said in LB, he does this shit all the time so he can publicly change his mind for ultimate persuasion effect.
He's garnering the support of people who think Q is BS, once they start listening he'll start talking about proofs.
Just watch.
In this periscope, Scott talks about meeting POTUS.
He specifically won't mention what he was there for, what was discussed, or who else was there.
I think he may have only mentioned Q once in a periscope before meeting with POTUS, only to say "I'm not ready to talk about Q yet"
After the meeting he's mentioned Q several times, this is a persuasion effect.
No matter what he says ABOUT Q he's telling you to think about Q ("Whatever you do, don't think about elephants")
