Agreed, but I don't think Pence will be the answer as he is part of the 'illegitimacy' of this administration. If Trump is impeached and convicted the 'stank' will be all over Pence and the GOP.
May have to go all the way down to the SOS in the succession line.
Rex at least doesn't seem as though he could be as easily lied to as Pence was by Flynn.
