A little more than 2 pages, basically saying to the Intelligence Community, your report on foreign election interference is not accurate, and it is also fundamentally dishonest.
Ratcliffe cites 1960-s era precedent. The Intelligence Community assessed that Russia was unlikely to deploy missiles to Cuba. The dissenter at the time was correct, and the Intelligence Community was incorrect.
So basically this is saying that the IC, specifically the CIA, had credible intelligence that China was indeed actively making efforts to influence the election, but since it helped their guy, they suppressed it.
Treason, anyone?
I do find the former DNI Grenell’s take on things worth hearing, though.
