Since Trump intends to replace virtually all of those 'intelligence briefers' with those selected by his National Security Advisor and his Head of the CIA and is being closely advised by a recent former head of the Defense Intelligence Agency, and has some discussions yet pending with the Head of the FBI, I am not too concerned if he lets his VP go to those meetings. 

He isn't going to pay attention to them after he is sworn in, either.  They will have found other employment by then.  In Hillary terms, it's known as "Regime Change".
