So what you're saying is that there isn't any more evidence that the Comey memo was leaked prior to President Trump's "tapes" tweet than there is that President Trump colluded with the Russians.
It may be true that the NYT had the Comey memo on May 11, but you need evidence before you make these allegations. Keep digging for the evidence. Until then, as recent events have shown us, a healthy skepticism is warranted.
Who else could claim to know what was said besides Comey ?
Comey had more than one memo, and the contents of one of the memos (not the "drop Flynn investigation" order memo) was published on May 11.
Comey leaked before the "tape hope" tweet. You might argue over what he leaked before, but no question he leaked before.
