Marco Rubio is off the fence on Tillerson. In a lengthy Facebook message, he outlines his concerns about the secretary of state nominee, but says he'll vote yes.
[D]espite my reservations, I will support Mr. Tillerson's nomination in committee and in the full Senate.
Note: Rubio's message promises to cause trouble for deputy nominees under Tillerson.
Why it matters: Rubio was the last potential problem for Tillerson, who should cruise his way through the Senate.
