US President Donald Trump has nominated the country's ambassador to Canada, Kelly Craft, as its next United Nations representative.
It comes a week after US State Department spokesperson Heather Nauert withdrew her nomination.
Nauert said the past two months had been "grueling" for her family, and she was therefore withdrawing her name.
"It is in the best interest of my family that I withdraw my name from consideration", she said.
The US Secretary of State Mike Pompeo said at the time: "Her personal decision today to withdraw her name from consideration to become the nominee for United States Ambassador to the United Nations is a decision for which I have great respect."

Commenting on Craft's nomination, Mr Pompeo said: "Ambassador Craft has been an outstanding advocate for America's national security and economic interests in Canada and she is extremely well-qualified to do the same at the United Nations.
"I look forward to her confirmation and continuing to work with her at the United Nations."
President Trump nominated Craft to be the US ambassador to Canada, and she was formally sworn in in September 2017.
She has served on the University of Kentucky Board of Trustees, and co-founded the Morehead State University Craft Academy for Excellence in Science and Mathematics.
In the private sector, she founded a successful marketing and business advisory firm.
In 2007, US President George W Bush appointed Craft as an alternate delegate to the UN General Assembly.
She is a graduate of the University of Kentucky and holds an Honourary Doctorate from Morehead State University.
She and her husband, Joe, share six children and eleven grandchildren.
