Yes and No. Technically he is responsible to carry out POTUS policy but..... Like I emphasized before Pence is the RINO brought in to balance the ticket.
He represents the political machine that has taken over the White House apparatus and kicked Bannon and others out.
When the First Amendment was attacked by Tim Cook of Apple and the other corporate giants, Pence caved as governor of Indiana.
Mike Pence backed down on freedom of religion and speech for gay marriage dissenters in 2015 along with other governors under similar pressure before and after him.
