According to this report from The Conservative Tree House,
Bill Priestap is cooperating.
When you understand how central E.W. “Bill” Priestap was to the entire 2016/2017 ‘Russian Conspiracy Operation‘, the absence of his name, amid all others, created a curiosity. I wrote a twitter thread about him last year and wrote about him extensively, because it seemed unfathomable his name has not been a part of any of the recent story-lines.
E.W. “Bill” Priestap is the head of the FBI Counterintelligence operation. He was FBI Agent Peter Strozk’s direct boss. If anyone in congress really wanted to know if the FBI paid for the Christopher Steele Dossier, Bill Priestap is the guy who would know everything about everything.
