President Trump has nominated U.S. envoy to North Korea Stephen Biegun for the deputy secretary of state post, AP reports.
The big picture: Biegun, who would replace John Sullivan if confirmed by the Senate, aided negotiations for Trump's historic meeting with North Korean leader Kim Jong-un, per AP, and has led ongoing negotiations to denuclearize the country. No president in recent history has started his tenure with as many extended Cabinet vacancies as Trump.
