That graphic, if real, explicitly states that he was personally told that directly by Cawthorne.
Sure, he might be making it up or lying, but...what is more likely:
Cawthorne exaggerating publicly about cocaine fueled orgies that didn’t happen and then admitting what he did after being called out by McCarthy, or...Cawthorne being pressured by leadership to keep his mouth shut?
I go with Cawthorn exaggerating/lying. His story is completely ridiculous. He has taken stories about drug use, etc., that he heard and inserted himself in them as a first person witness. One of the most common forms of lying.
