WASHINGTON (Reuters) - U.S. President Donald Trump on Friday said he would nominate State Department spokeswoman Heather Nauert as the next U.S. ambassador to the United Nations, choosing a former TV anchor with little policy experience to lead U.S. diplomacy at the international organisation.

Nauert, whose nomination requires U.S. Senate confirmation, is a former Fox News Channel correspondent.

Trump also told reporters at the White House that he would make another staffing announcement on Saturday involving the Joint Chiefs of Staff, but gave no other details.
