Is it strange to anyone else that he briefed Pence on the conversation rather than Trump?
Pence is a shark. He will undermine Trump first chance he gets because he won’t be able to become President through elections. This is, “house of cards” level corruption
No because the POTUS is not always available for briefing. That is one of the functions of the VP is to assist the President in the day-to-day operations of the gov’t.
