I’m guessing they know what’s coming.

Eric Chewning, chief of staff to Defense Secretary Mark Esper, is stepping down at the end of the month, the latest in a series of high-profile civilians to leave the Pentagon.

He’ll be replaced by Jen Stewart, the top Republican staffer on the House Armed Services Committee and a former top adviser to the chairman of the Joint Chiefs, according to a statement from Pentagon spokeswoman Alyssa Farah.

Chewning, a former Army intelligence officer and combat veteran, has managed the day-to-day operations of the Office of the Secretary of Defense through a historic number of leadership changes, working for four Pentagon chiefs.

Politico then writes a basic biography for this guy and a timeline for his time in the Pentagon, but I doubt most of us care about that since this is likely the last time we will ever hear this guy’s name.

The important part is right here: 

Chewning was featured in a recently released trove of unredacted emails that show Pentagon officials’ concerns with the legality of White House moves this summer to hold up military assistance to Ukraine, an issue at the center of President Donald Trump’s impeachment.

In the emails reported by Just Security, Chewning in late August relayed to acting Pentagon comptroller Elaine McCusker questions from defense contractor L3Harris Technologies about the status of the Ukraine funding. McCusker criticized the Office of Management and Budget for saying the freeze wouldn’t prevent the aid from being fully spent.

Chewning later wrote that a memo to OMB, which warned that the Ukraine aid was in danger of not being fully spent by the end of the fiscal year, will have to wait until after a September meeting between Vice President Mike Pence and Ukrainian President Volodymyr Zelensky in Poland.

“We expect the issue to get resolved then,” he wrote to McCusker. “If not, I think we need to send the letter.”

His departure comes after a string of senior officials left the Pentagon last month or announced they were stepping down, including the director of Defense Advanced Research Projects Agency, the acting undersecretary for personnel and readiness, the principal deputy undersecretary for intelligence, and the assistant secretary for Asian and Pacific security affairs.

So Chewning was part of that explosive email string about the Ukraine kerfuffle.

Clearly that is why he is jumping ship.

Though I imagine that he is now on the Democrat’s wish list for witnesses to testify at the Senate impeachment trial.
