Facing questions about her political ambitions, the outspoken and charismatic diplomat said yesterday that "there is going to be chatter about things."
Asked if she wanted to be secretary of state, Haley gave a definitive-sounding "no I do not."
Secretary of State Rex Tillerson's tenure at the State Department has been a rocky one, with diplomats uneasy at promised budget cuts and suffering low morale.
Haley was considered a potential running mate for Trump in 2016 and is tipped as a possible future presidential candidate herself.
"What I'm trying to do is do a good job and I'm trying to be responsible in my job and I'm trying to make sure that I inform the American people of everything that I know."
"I'm trying to serve the president and this country the best I can, and if people want to take it to mean something else, that's their issue," she said.
