Trump picks Heather Nauert as U.S.' next UN ambassador and William Barr the next ...

U.S. President Donald Trump has announced he will nominate State Department spokesperson Heather Nauert as the new U.S. Ambassador to the United Nations (UN).

Heather Nauert, 48, was an American journalist at Fox News and has been the government official spokesperson for the United States Department of State since April 24, 2017.

Before then she had rarely participated in government affairs, except for her two elections as South Carolina governor.

It came two months after Nikki Haley, the 46-year-old U.S. former United Nations Ambassador, applied her resignation on October 9.

Meanwhile, Trump also says he will nominate William Barr, attorney general under President George HW Bush, to lead the Justice Department again.
