I am not surprised by

Guo Wengui insulting him with vulgar and obscene language ( as he always do to other oversea Chinease anti CCP activists) after Guo used him.  But an old grandpa coming to US for anti-CCP movement, being used then treated by Bannon like this, made me really look down on Bannon's 人品 although I like many of Bannon's political views.

One possible reason: Guo & Bannon didn't get enough money from 袁 as they expected...
