WASHINGTON (AP) — New national security adviser John Bolton is taking the helm of the National Security Council at a time of tumult on President Donald Trump's team and with a long to-do list awaiting him. WASHINGTON (Reuters) - South Korea’s national security adviser was in Washington on Wednesday for his first meeting with his new American counterpart, John Bolton, U.S. officials said, amid preparations for separate U.S. and South Korean summits with North Korea. Another high-ranking National Security Council staffer is leaving the White House as new National Security Adviser John Bolton makes his mark. And on Monday, he appeared at his first Cabinet meeting, where Trump talked up his forthcoming meeting with North Korean leader Kim Jong Un, chided China for taking advantage of the United States and condemned the "atrocious" chemical attack in Syria. There have been many such shake-ups, even in just the past few weeks. It was unclear whether any of Bolton's favored candidates were being hired. White House deputy national security adviser for strategy Nadia Schadlow has resigned amid newly-installed John Bolton's ongoing shake-up of the National Security Council. Nadia Schadlow is the third senior national security official to leave the White House since President Trump named John Bolton as his national security adviser to replace H.R. “But I wanted ‘line’ responsibility — to manage something and to change it, not simply to be ‘staff,’ even at the White House.”

Bolton’s start comes after the tortured exit for McMaster, Trump’s second national security adviser, a three-star general who never developed a strong personal bond with the president.
