President Donald Trump said Thursday National Security Adviser H.R. McMaster is resigning, and will replace him with John Bolton—a foreign policy hawk who has openly backed war against Iran and North Korea. Bolton will take over the position on April 9 and will not need to be confirmed by the Senate. In 2005 and '06, Bolton served as U.S. ambassador to the United Nations, after President George W. Bush named him to the post as a recess appointment, amid fears he would not be confirmed by the Senate. Bolton is a senior fellow at the American Enterprise Institute and in recent years has made regular appearances on Fox News. Just three weeks ago, Bolton wrote an op-ed for The Wall Street Journal headlined “The Legal Case for Striking North Korea First.” We'll have more on John Bolton after headlines with investigative reporter Gareth Porter.
