WASHINGTON (Reuters) - President Donald Trump will nominate State Department spokeswoman Heather Nauert as U.S. ambassador to the United Nations, two White House officials said on Thursday, tapping someone with no prior policy or political experience to deal with some of the world's thorniest issues.

The decision was expected to be announced on Friday morning, the officials said, requesting anonymity.
