Records obtained by The Associated Press show the Republican nominee's departure was anything but smooth, though.
E-mails between Haley and her bosses show she did not want to leave or take a hiatus, as offered.
After a negotiation between attorneys, Haley, of Lexington, left with $35,000 severance and a promise from administrators they would say nothing to embarrass her or question her integrity.
Her 11/2-year job with Lexington Medical Center, which she held while a state legislator, has come under fire from her opponent, Democratic Sen. Vincent Sheheen, and from some GOP activists, who question why she got the job, its salary and the donations the foundation received during her tenure.
Her campaign spokesman defended her work.
"A big part of Nikki's job was to get as many different people and organizations involved in the foundation as possible," Rob Godfrey said Friday. "She did that, and she did it very well, by continuing existing foundation relationships and building new ones. Some of those involved groups and companies that have lobbyists, but, as the Ethics Commission makes quite clear, Nikki working with them to grow a nonprofit, community-focused organization is entirely proper."
To back that up, the campaign forwarded an Oct. 1 e-mail to its attorney from the commission, saying that nothing in state law prohibits a public official from asking a lobbyist to give to a charity.
Under the April 23 agreement to part ways, Haley received nearly three months worth of salary, $27,200, plus $8,000 for unused vacation pay.
Days later, her campaign and hospital spokespeople said, she left voluntarily, after a successful February fundraising event.
