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.

Marco Rubio was sworn in on Tuesday as the nation's 72nd secretary of state, the first of President Donald Trump’s Cabinet nominees to take the job. Rubio said Trump’s primary priority will be furthering the United States’ interests and that anything the government and State Department do must make the country stronger,

He’s being undermined by fellow Republicans, and that’s before he shows up to lead a workforce Trump distrusts.
