I have to wonder how much Barr and Wray knew? The silence is deafening.
Cia and fbi were not told. From what I read from an earlier article.
Barr has expressed separately a recognition and warning with respect the CCP ambitions. DOJ involvement with the 2020 elections will most likely involve criminal referrals and take time properly to develop. Best not to infer inactivity from a lack of leaks.
