Sen. Rand Paul, R-Ky., doesn’t like Donald Trump’s rumored finalists for the job of leading the State Department, and said he is “not inclined” to support either of them.

Former New York City Mayor Rudy Giuliani is the rumored favorite for the job, and John Bolton, former U.S. ambassador to the United Nations, is another option. But Paul told the Washington Post that he doesn’t like either and will do “whatever I can” in particular to block Bolton.
