As President Donald Trump steps up efforts to engage North Korea in nuclear disarmament talks, the State Department is in the most turmoil since the president's inauguration, CNBC reported.
The latest upheaval came Tuesday with the sudden firing of Secretary of State Rex Tillerson, who was dismissed with few details provided by the White House. Trump picked CIA Director Mike Pompeo to be the next secretary of state.
The moves followed Trump's abrupt announcement last week of a yet-to-be-arranged meeting with North Korean leader Kim Jong Un.
But the prospects for any diplomatic breakthrough are clouded by senior State Department vacancies, including a permanent U.S. ambassador to South Korea. The Trump administration has also yet to fill other positions critical to any talks with North Korea, including a permanent undersecretary for arms control and international security affairs.
