That’s just plain wrong, and an example of hive-mind thinking that less intelligent people easily fall into.
Bannon drew a direct line between Trump and treasonous behavior. There are only two possible explanations: A, Bannon sincerely believed that a short, legal meeting Trump Jr participated in implicated both Jr and Trump Sr in treason, or B, Bannon was trying to destroy Trump.
Unless you believe Bannon is a drooling moron, the all but certain explanation is B. That would make it at least the second time Bannon had tried to destroy Trump, the first being when he tried to link Trump directly to organized crime.
