The Washington Post claims that Trump has drawn pictures before and in fact 4 such pictures have been auctioned.
One of the pictures allegedly drawn by Trump in 2006 was a sketch of the George Washington Bridge in Manhattan. Coincidentally, that picture looks just like the picture drawn by the robot Sonny in the movie iRobot.
Not sure what to make of it, but sure is weird.
