Comey has been leaking all along anyway. Trump's bluff forced Comey to admit under oath that he had told Trump three times that he wasn't under investigation. You think he would have admitted that if he didn't think Trump might have tapes?
So now the witch hunt has moved on. Now its focused on whether Trump might have committed the terrible crime of obstructing a witch hunt
Comey actually said "Trump isn't under investigation...at the present time."
So the witch hunt goes on for months based on the bogus Russian dossier and the dodgy Crowdstrike report (anyone investigating why the DNC refused to allow the FBI to examine their servers) and after all those months finds nothing that would warrant puttingTrump under investigation. Comey confirms this (in private despite being happy to leak all other kinds of tidbits).
So now the witchhunt is forced to move on to the question of whether Trump obstructed a witch hunt based on an interpretion of Trump's words to Coimey
