In the end Rubio thought better than to be the lone Republican obstrucing a Republican president
In a 11-10 vote Senators in the Foreign Relations Committee approved Rex Tillerson’s nomination as Secretary of State.
All Foreign Relations Committee Democrats voted against Tillerson, all Republicans voted for him.
The neocon Marco Rubio who attempted a grilling of Tillerson over Russia in the hearings, and refused to express support for Tillerson until the last minute, could have swung the vote, but that would have left him as the lone dissenting Republican voting with the Democrats. Apparently in the end he opted not to stray from the safety of the herd.
The way is now clear for a vote of the full Senate to confirm Tillerson.
