Taylor's statement clearly states he has first hand knowledge about what happened in both the formal channel and the informal one. The only thing he didn't have at the time was the transcript of the partial phone call released by Trump. All of this is pretty damning first hand evidence of what transpired. We do not yet know what  happened when Taylor and others were questioned behind closed doors. We do know that Taylor, a non-partisan, a civil servant with 50 years of service, who first served under George Bush, was extremely horrified and disturbed by what was going on in the unofficial channel.

In short, there was a quid pro quo.
This we now know.
Period.
