Secretary of State Marco Rubio, in a memo reviewed by NBC News, said additional guidance would be issued on existing passports containing an “X” sex marker.

Tensions between the U.S. and China have been rising for some time now, and Rubio's appointment has widely been seen as a sign that Trump plans to maintain a hard line on China during his second term.

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.
