He posted a video that was exactly 51 seconds long, and the Q Post for that number reads as follows:
Dear Patriot.
We hear you.
We hear all Americans such as yourself.
The time has come to take back our great land.
The time is now.
Rest assured POTUS is backed by the absolute finest people alive who are all dedicated to the eradication evil and corruption from the US/World.
Find peace.
God is with us.
God bless and be safe.
-The WH

Initially, I would have dismissed the time length of the video as coincidental, but that is such a weird place to cut the video... video ends in the middle of a sentence/thought and could have been clipped much shorter. Other message is the part about america's come back starting now.
