Not sure if these have been posted, probably fake, but the twitter for KJU and his sister are getting interesting. Eyes on.

Upon closer review, I think they're fake.
This Trump tweet doesn't appear to exist.
KJU's account is from 2009 though. Playing the long con perhaps. Sister's account is only 2 months old, and very active so far. Smells larpy.
