Summary
That alliance seems as steady as ever, even as the rumors fly that the president is about to throw Tillerson overboard in favor of U.S. Ambassador to the U.N Nikki Haley.
Tillerson initially peeved Trump by leaning the other way, arguing that this dispute should be mediated. But by this month, Trump seemed to have come around to Tillerson's viewpoint and was talking on the phone to King Salman and in person to Qatar's ruling Sheikh Tamim bin Hamad al-Thani to say that it was time to resolve the dispute.
Trump still leans toward Riyadh, but he knows that Tillerson and Mattis have a united front on this issue, as on most others.
Trump may get angry, as after Tillerson's comment that the president spoke for only himself after the Charlottesville unrest. But it's said that Trump watched the video of Tillerson's remarks three times and decided he was "OK with them," though he may still be quietly grumbling.
Apparent (unfortunate) message: Tillerson didn't want another open dispute with the president.
