Tillerson's jaw-dropping comments on TV today will likely only worsen their relationship.
Fox News Sunday moderator Chris Wallace asked Tillerson about Trump's response to the racist carnage in Charlottesville.
Tillerson replied: "I don't believe anyone doubts the American people's values or the commitment of the American government, or the government's agencies to advancing those values and defending those values."
Wallace asked the obvious follow-up question: "And the president's values?"
"The president speaks for himself," Tillerson said.
Wallace looked stunned.
