I agree, and I hate it when people post videos without telling us what it's about, but I decided to watch it. It summarizes the known information that points at Ciaramella as the whistleleaker.
After watching it, my intuition is that everyone involved in this are proxies for Ukrainian gas companies interests. There are lots of extremely wealthy people involved that don't want an investigation of Burisma and it's associated criminal associates, and this Ciaramella guy is acting as one of their agents in an effort to stop Trump from investigating and exposing the criminal doings of these people.
It’s amazing how this guy got all this information into just 14 minutes.
“14 minutes Puts it all together” I thought was summary enough, ..sorry all.
