Earlier, Petraeus said that he is willing to serve in President-elect Donald Trump’s administration if asked, as reports emerged of Trump considering him for the post of defense secretary.
General Petraeus commanded US and NATO troops in Afghanistan and multinational forces in Iraq, before retiring from the military to take a position in the Central Intelligence Agency (CIA) in 2011. He resigned as the CIA director in 2012 following a scandal over Petraeus' extra-marital affair with his biographer Paula Broadwell.
Trump also considers former Massachusetts Governor Mitt Romney and ex-New York City Mayor Rudy Giuliani for the job.
On Friday, US Congressman Dana Rohrabacher stated in a Twitter post he was also under consideration to join the Trump administration as secretary of state.
