Jeff Sessions has left the Justice Department for his last time as attorney general.
Sessions walked out Wednesday evening to applause from more than 150 employees who gathered in a courtyard at the Justice Department.
As he left, Sessions appeared emotional and said, "Thank you" and "God bless," before hopping into a waiting SUV.
He also shook hands with his chief of staff Matthew Whitaker, who was appointed acting attorney general on Wednesday after Sessions resigned at the president's request.
Whitaker told Sessions: "It's been an honor, sir."

In a tweet Wednesday, Collins expressed concern about the administration's announcement that Deputy Attorney General Rod Rosenstein will no longer be overseeing the probe into possible coordination between Trump's 2016 Republican campaign and Russia.
She tweeted: "It is imperative that the Administration not impede the Mueller investigation." She added: "Special Counsel Mueller must be allowed to complete his work without interference_regardless of who is AG."

Rep. Elijah Cummings of Maryland says it is not acceptable if President Donald Trump requested Sessions' resignation to interfere with the special counsel investigation into Russian election interference and possible coordination with Trump associates.
Sessions announced his resignation Wednesday.
Cummings is also pushing for Congress to "confirm" that Acting Attorney General Matthew Whitaker is recused from overseeing the investigation. Whitaker is expected to oversee the investigation despite being critical of it in public statements and chairing the campaign of a witness in the probe.
Cummings is set to chair his committee in January when Democrats take control of the House.
