So Sondland is sitting at a restaurant table, calls the President, and puts his phone on speaker? Seriously?
Oh, hello Mr President! You caught me out to dinner, let me put you on speaker!
Yeah, not buying it. So at best, the “aid” heard one side of the convo. Also quite possible the call never happened. If it happened there is some kind of record of the call, and it’s almost certain POTUS was not alone when the call took place.
