It is interesting. Mike Pence has been sidelined for some time now – you very rarely see him with Trump like you did Biden with Obama.
Pence has shown his sycophancy to Trump – the best survival strategy in this administration – but in my opinion he and Trump do not gel on a personal basis. Pence is ambitious and would like to be President, so perhaps this is the start of his covert bid, disguised as ‘protecting America’s interests’.
Pence could be bitter about the way he is being treated by Trump. This op ed is a very effective tool at getting a degree of revenge.
