You use the word standard for a constitutional process that has only been applied to 3 presidents. Impeachment is a constitutional process and democrats are following what is in the constitution. Trump trying to block testimony and documents clearly isn't a principled stance. He's not a king nor above the law. And really how does it make sense to you that he wouldn't want his people testifying and documents released? After all in your world it would clear him. I think you know otherwise though. Sadly most of your party seems willing to support and protect the corruption as he faces no pressure from republicans to follow the law. Subpoena's are apparently okay to ignore if you don't want to.
