You could literally say the same thing about the Steele Dossier sponsored by the Clinton Campaign, Steele was identified as connected to a foreign government influence campaign as well. A candidate literally cooperated with a foreign actor with undisclosed Russian ties to generate evidence against their opponent which they knew would be disseminated by the American IC. Not having these protections just incentivizes whoever currently controls the apparatus to strategically investigate their party's opposition.
Steele is very publically a former MI6 agent, and while the British are our allies, that counts in and of itself.
However, it's also fact that Steele himself was well known to Russian intelligence, and while it's clear he was no friend to them he was a known enemy - They were specifically trying to feed him disinformation[1][2]
Did he bite bad bait? That's the question that doubters bring up. The "pee tape" thing is so bizarre I think it's likely true, but on the other hand I think that at this point Trump could just own it.
It isn't about POTUS, it's about the notion that preventing US counter intelligence from doing their jobs with respect to illegal influence on political campaigns. If what you say is true, and the Clinton campaign was seeking foreign assistance, shouldn't we know about and prevent that?
