Tom Cotton is the current Senator from Arkansas and considered extremely pro-military.
Cotton’s tenure in the Senate was thrust into the national spotlight last year during the contentious Iran deal negotiations. Cotton was a vocal critic of the deal, arguing it would do little if anything to stop the rogue nation from developing nuclear weapons.
President-elect Trump has also bashed the Iran deal, and has promised to renegotiate a better deal, or at the very least tear up the current one. Given Cotton and Trump’s similar views on Iran, it seems like the Oklahoma Senator could be a strong pick for Secretary of Defense in the new administration.
