Nikki Haley is resigning as the U.S. ambassador to the United Nations and will leave the Trump administration at the end of the year, she said Tuesday.

It is not immediately clear what prompted the move. She informed her staff Tuesday, NPR's Michele Kelemen reports.

Haley appeared with President Trump on Tuesday morning at the Oval Office, where he called her a "fantastic person" and said Haley had told him six months ago that she might take time off at the end of the year.

President Trump defended his "America First" agenda in a speech to the United Nations General Assembly on Tuesday, in effect spiking the football at what his secretary of state described as the "Super Bowl of diplomacy."

The president boasted that he's accomplished more during his time in office than almost any previous administration — a claim that drew immediate laughter from the assembled diplomats and other world leaders.

Trump pressed ahead, undaunted.

"I didn't expect that reaction, but that's OK," he said.

When President Trump delivers his speech to the United Nations General Assembly on Tuesday, one phrase is unlikely to show up: "rocket man."

A lot has changed since Trump used that derisive nickname for North Korean leader Kim Jong Un during his address at the U.N. last year — remarks where he also said the United States would "totally destroy" North Korea if necessary.

Japan's Prime Minister Shinzo Abe, in New York this week for the U.N. General Assembly session, says he had a "very constructive" dinner meeting with President Trump at Trump Tower, where the leaders discussed trade and military ties.

Abe, who won re-election as leader of his Liberal Democratic Party last week, told reporters in New York that during their Sunday dinner, the two also reaffirmed their commitment to denuclearization of the Korean peninsula.
