Both sides agree that it will be Trump who decides if Rubio is MAGA enough to remain a member of his administration and represent his views around the world. He unceremoniously fired his first secretary of State, Rex Tillerson, via tweet, and has long made clear he views foreign policy as his domain.

U.S. Senator Marco Rubio from Florida became the first of President Donald Trump's cabinet nominees to be sworn into office on Tuesday, where he emphasized that U.S. foreign policy under Trump will put American needs first.
