It's been said that Feinstein released it accidentally, by sending the wrong thing by email to the wrong address, or some similar senior moment. She's already done that more than once in other connections.
Yeah, right. Anyone who believes that BS is certifiable. First, I doubt that this 85 year old dinosaur even knows how to email anything. This is no senior moment, but rather, a calculated strategy to keep this quiet until after the hearings ended.
Feinstein "mistakenly" leaked the closed-door testimony of Glen Simpson (Fusion GPS). The real reason it was done was to inform the various players in this scam what Simpson said so they could react appropriately and sing from the same sheet of music. Feinstein is corrupt. Her husband has made a bundle from his and her Chinese connections, including the Chinese spy on her payroll for 20 years.
