I think one of the key elements that is new is, if I recall, on page 8, section 4. It is one of the sections not highlighted.

What is mentions is the trade-off in "intelligence," and I use that term loosely. Apparently Trump has access to personal information about Russian emigrees and oligarchs that move around in his elite circles, and the Kremlin wants to keep tabs on these people. So Trump was providing that type of information on a tit-for-tat basis that Russia continue to help him out where it could.

If that is true, then it is actually close to treason. I'm pretty sure technically it's not, at least not nowadays, but just a few years ago that would have been worth a life sentence. There are probably still Americans in jail for having done something like that in the 70's or 80's.

Anyway, it is a huge deal if your commander in chief has been in the habit of trading intel on Americans or people in America, for personal gain.
