Are you kidding me? Bryan Pagliano? He ignored a HOUSE request, and the House Oversight Committee was run by the GOP at that time. If that subpeona wasn't enforced, you can blame Chaffetz, not the Democrats.
Also, you're neglecting to mention that he had immunity from the FBI already. There was no actual point in bringing him in. And that Clinton publicly pleased with him to cooperate.
Seriously, what is wrong with you?
