LONDON, Nov 23 (Reuters) - Retired U.S. general David Petraeus indicated on Wednesday that he would serve in President-elect Donald Trump's administration if he was offered a job, according to an interview on Britain's BBC radio.
The Wall Street Journal has reported that Petraeus, who resigned as CIA chief in 2012 after an extra-marital affair was revealed, was under consideration for the post of defense secretary.
Asked if he would agree to serve in the Trump administration, Petraeus said: "I've been in a position before where a president has turned to me in the Oval Office in a difficult moment and .... said 'I'm asking you as your president and commander-in-chief to take command of the International Security Assistance Force in Afghanistan'.
