An effort was made to keep this quiet. The transcript, and a more detailed one, were squirreled away in a more secure digital storage where classified sensitive documents reside. Not politically sensitive for Trump, but national security sensitive, which this is not.
The Justice Department orchestrated efforts to deny Congress access to this whistleblower complaint. The Inspector General interviewed some of the potential witnesses listed by the whistleblower, and found his complaint to have merit. This, too, there was an attempt to hide.
That you'd cherry pick these out of the conversation isn't surprising. But rebutting it isn't a debate or discussion. If one side will ignore facts for the convenience of a pretense at rational argument, it stops being a debate.
You show me honest effort to grapple with all the facts here, and you might change my mind. This post, however, tells me that is unlikely.
