McCain said Friday that he does not expect to make his decision “for the next few weeks,” and much will depend on how the committee lineup shakes out on Foreign Relations and other Senate committees. “It would be like my third or fourth committee,” he noted, which would require a waiver from Republican leadership, though that’s something he thinks he could get. McCain currently serves on Armed Services; Health, Education, Labor and Pensions; Homeland Security and Governmental Affairs; and Indian Affairs.
The Foreign Relations slot should be there if he wants it — and if the leadership acquiesces. Of the nine Republicans currently on the panel, the only two who are highly likely to return next year are Corker and Sen. Marco Rubio, R-Fla.
