U.S. Education Secretary Arne Duncan is expected to resign from his position in December.
A source at the White House told the Washington Post, "We can confirm that President Obama will announce today that Education Secretary Arne Duncan intends to step down in December, and that the President has selected John B. King Jr., who currently acts as Deputy Secretary of Education, to replace him."
Duncan, former Chicago Public Schools CEO, has served as U.S. Education Secretary under the Obama administration since 2009.
In an email sent to his staff on Thursday announcing his pending departure, Duncan said, "Serving the President in the work of expanding opportunity for students throughout this country has been the greatest honor of my life."
Duncan said he plans to move back to Chicago after he steps down in December.
"I imagine my next steps will continue to involve the work of expanding opportunity for children, but I have no idea what that will look like yet," he added.
