The Director of the CIA, Gina Haspel, announced her resignation from her job, on the last day of the outgoing president, Donald Trump, at the White House.
"It has been the greatest honor of my life to lead this remarkable organization," Haspel said in a statement carried by the agency via Twitter.
"I depart deeply proud of the work we have done together- the triumphs we have achieved, the threats we have overcome, and the investments we have made for the future," she added.
"The CIA team thanks Director Haspel for her 36 years of dedicated service to the American people.
"She has broken barriers and empowered the next generation of CIA officers," the agency said in a tweet attached to Haspel's statement.
Although Haspel did not mention the reason for leaving the position, the American "Axios" website had reported that it had threatened to leave the agency's administration, last December, after US President Donald Trump's intention to appoint Cash Patel, the former assistant Republican, Devin Nunes, as her representative.
Instead, Trump has decided to appoint Patil as acting chief of staff of Defense Secretary Chris Miller, according to Axios.
Miller's appointment to the post came after Defense Secretary Mark Esper was fired, following the announcement of the US election results.
