Its a biased memo from a biased group of senators. Just a really fancy opinion piece with no proof of anything. Much like the 49 investigations republicans did into Hillary all for the same thing and always seemed to expect a different result. The only purpose of the investigations was a smear job. Same is happening now with investigations on FBI officials and pretty much headlined by the same ones who wasted hundreds of millions investigating Hillary.
also, since when is a partisan memo relevant??? lets have unbiased investigations run the course. in the end, the do have a judicial system as part of society, they need to be able to do their job. and if any findings from various investigations inform the public, ehy would that be a bad things? freedom of information!!!!
