Washington DC: In a sudden move, Indian-American US Ambassador to the United Nations Nikki Haley resigned Tuesday, becoming the latest casualty in the fragile Trump administration just weeks ahead of the crucial mid-term elections.
President Donald Trump has accepted her resignation, US media reported.
Trump has tweeted that he has a "big announcement" with Haley in the Oval Office at 10:30 a.m. The reason behind her resignation was not immediately clear. Haley, 46, was the senior most Indian-American official in the Trump administration.
She was confirmed as UN Ambassador four days after Trump was inaugurated in January 2017. She had scripted history by becoming the first-ever Indian-American to be appointed to a cabinet-level post in any US administration.
The daughter of Indian immigrants from Punjab, Haley was the first woman tapped by Trump for a top-level administration post during his transition to the White House.
Haley's nomination was a turning point for the Indian-American community which is increasingly playing greater role in American politics.
She was critical of Trump during the primary campaign and had backed Senator Marco Rubio in the Republican primary.
