And why should the Secretary of State NOT be on a phone call with a foreign leader?
No reason, but Schiff-Nadler-Pelosi want him hauled before House committees so that their news dogs can portray him as they want, not as he is.
The key is control of the news cycle. The facts, the truth be damned. They are writing the narrative and acting it out just as Schiff read bald faced lies into the Congressional Record before realizing the President would indeed release the transcript. They’re making it up and having their news machine validate it as if it was fact.
