Senator John McCain, a Republican from Arizona and chairman of the Senate Armed Services Committee, speaks during a hearing in Washington, D.C., U.S., on Thursday, Nov. 30, 2017. McCain said in a statement Thursday that he's decided to support the Senate tax bill. McCain hadn't taken an official position on the tax plan until now -- and no one was taking his vote for granted after he shocked the political world by voting against a rushed attempt to demolish the Affordable Care Act this summer.
