The first day I heard the word “whistle blower” on TV? I immediately said to myself, “I bet it was John Bolton”. Because he loves defense spending, (like John McCain) and Trump was talking about pulling out of constant ongoing wars.
So I figured him and Trump didn’t get along, and Trump fired him. So it made sense tome, that Bolton would want to get even with Trump. I have nothing against Bolton, I like him after reading an NRA interview with him long ago. He supports guns and gun owners.
