So it was “exposed” that the stupid man with a fragile ego is easy to manipulate … I think that most people, who are not in the alternative fact news bubble, knew this for years already. People have been widely comparing him to a toddler since his first year as president, and those people include his own aides/appointees. It was so common that someone even wrote a book about it: https://press.uchicago.edu/ucp/books/book/chicago/T/bo51128380.html.

So imo “exposed” is the wrong word, something like “demonstrated yet again” would have been better.
