I suspect Q left a message in wikipedia article "King Tower".

The article was edited two times:

en.wikipedia.org/w/index.php?title=King_Tower&diff=824562668&oldid=824562132

en.wikipedia.org/w/index.php?title=King_Tower&diff=824562132&oldid=824561914

"It is currently home to everyones favorite ex-US President, current inmate, Barack Obama."

I don't know if it is a joke created by an anon. But the timestamps maybe interesting.
