Thank you both.
As Chief of Staff Newt could give Trump excellent advice but from Newt’s POV that job would be too much work and near zero recognition. He has too many things of his own going on to get shoved behind a curtain. As VP he could not only advise he could also circulate as spokesperson, diplomat and the VP’s normal role as President of the Senate.
And he's not out for the lime light.
Think you have him all wrong.
Someone usually sits in for the VP in the Senate except for a needed vote.
VP has no set bounds.
Chief of Staff is most likely....but VP is fine, too.
