YES. Do release the evidence. Although... Coming from this administration nothing can be trusted.
There is none but since intel is neither confirmed nor denied in public, they can get a headline implying there is solid evidence with certainty that nobody in the intelligence community will (a) comment on it either way and (b) release whatever information they do have, refuting or supporting the claim.
Then this unsubstantiated conspiracy theory claim just sits out there on all those "real" news sites like CNN, NBC, etc.
