The SCIF is used for privacy in interviews whether classified info given or not. It gives all who participate more freedom to speak. Moreover both D and R have equal opportunity to ask questions with equal time. Your argument is shallow at best. And it had already been said all interviewees will return to open sessions in the public eye when SCIF sessions are completed.
You know, just like the R’s did during Benghazi hearings, and Clinton hearings and almost all other sensitive questioning of people have been done by Congress and Senate.
Again, your R party is full of shit wth regard to impeachment hearings - and while I’m at it, pretty much full of shit all the time.
