Amid murmurs she could again run for president, Secretary of State Hillary ClintonHillary Diane Rodham ClintonHouse Judiciary Committee subpoenas FBI agent who sent anti-Trump texts Clapper: Trump was serious when he said he wants citizens to act like North Koreans do for Kim Hillary Clinton: Fundamental rights are 'under assault like never before' MORE said Friday that her current post is likely her "last public position."

"No, I'm not," Clinton told an audience of students in Bahrain, according to Reuters. "I think I'll serve as secretary of state as my last public position and then probably go back to advocacy work, particularly on behalf of women and children."

But her remarks Friday are some of her most specific comments on her political future. 

Speculation surrounding Clinton's next move has swirled ever since she lost her closely contested race against Obama more than two years ago.

Talk accelerated when veteran Washington Post reporter Bob Woodward said in October that a 2012 ticket featuring Obama and Clinton as the running mate was "on the table" and again after Democrats were handed a series of defeats in the November midterm elections.

The Woodward report was also dismissed by the White House and Clinton. 

Clinton on Friday said the myriad responsibilities of the Oval Office can take its toll on presidents. 

"Every president, if you watch what they look like when they come into office, you can see their hair turn white because it's such a hard job," she said.
