Opinion speculation.
The claim this began before Mueller and they are deadly serious could be easily proven by pointing to the grand juries, indictments, arrests and convictions.
Comey, Brennan,Clapper,Yates,etc,etc, hauled before any grand jury? Any of them arrested?
If it doesn’t rain today does that prove it won’t rain tommorow, asking for a friend?
Lol...
Meanwhile in the real world
Clapper throwing Obama under the bus
“I’m alluding now to the President’s (TRUMP) criticism of President Obama for all that he did or didn’t do before he left office with respect to the Russian meddling. If it weren’t for President Obama, we might not have done the intelligence community assessment that we did that set off a whole sequence of events which are still unfolding today, notably, special counsel Mueller’s investigation,” Clapper said Wednesday on CNN.
"On Feb. 2, 2019, Acting Attorney General Mike Whitaker testified before Congress that Huber and others are part of ongoing investigations as we've previously been told. Whitaker Confirms Horowitz/Huber Investigations."
Department of Justice Hearing On Russia and Mueller Investigation
This is a video of Congressional (House Judiciary Committee) testimony by then Acting Attorney General Whitaker.
Whitaker confirms that both Horowitz and Huber are investigating and/or reviewing "matters" of which you are concerned.
Don't get bogged down in the difference between "review" and "investigation". They mean the same thing.
If crimes are discovered during a "review", recommendations for indictments will come down. Are you going to now say that Barr will ignore any such recommendations/referrals?
How deep does your denial go?
