White House communications director Michael Dubke was the latest to relinquish his post in the administration of President Donald Trump, resigning from his position Tuesday. Dubke originally tendered his resignation May 18, but offered to stay on while Trump went on his first foreign trip, according to Axios’ Mike Allen.

“It has been my great honor to serve President Trump and this administration,” Dubke wrote in an email to friends and associates Tuesday, according to Axios. “It has also been my distinct pleasure to work side by side, day to day with the staff of the communications and press departments.”

Axios ascribed Dubke’s departure from the administration as a “reminder of how hard it is for newcomers to thrive in Trumpland,” and reported that he had “never gelled” with other members of the team. Reports had recently emerged that Trump was dissatisfied with the work of his communications team after they struggled to handle the dismissal of FBI director James Comey, leading to speculation that White House press secretary Sean Spicer would be fired.

Trump reportedly told Spicer and Dubke earlier in May that they needed to “unify the White House’s communication strategy," according to The Hill.

Dubke’s resignation is merely the latest shakeup in the Trump administration. Not including the 46 prosecutors appointed by former President Barack Obama who were fired by Trump, the administration has had its fair share of internal turnover.

Acting Attorney General Sally Yates: Trump fired Yates January 30 after she refused to enforce the president’s ban on travel from several countries. Yates was informed of her dismissal by way of a handwritten letter, according to officials in the White House.

“[Yates] has betrayed the Department of Justice,” the White House said in a statement regarding the decision.

National Security adviser Michael Flynn: Flynn resigned as national security adviser February 13 after reports emerged that he had given “incomplete information” in regards to conversations he had with Russian officials in the weeks before Trump’s inauguration.

“Unfortunately, because of the fast pace of events, I inadvertently briefed the vice president-elect and others with incomplete information regarding my phone calls with the Russian ambassador,” Flynn wrote in his resignation letter. “I have sincerely apologized to the president and the vice president and they have accepted my apology. I am tendering my resignation, honored to have served our nation and the American people in such a distinguished way.”

FBI director James Comey: In perhaps one of the most shocking terminations of the presidency thus far, Trump fired Comey May 9. Trump originally said he acted on the advice of the Justice Department but later said he planned to fire Comey regardless of the recommendation of Deputy Attorney General Rod Rosenstein. In the ensuing controversy, Trump’s firing of the FBI director was slammed as reports emerged that the president allegedly asked Comey to shut down an investigation into former national security adviser Michael Flynn.

“While I greatly appreciate you informing me, on three separate occasions, that I am not under investigation, I nevertheless concur with the judgment of the Department of Justice that you are not able to effectively lead the bureau,” Trump said in a letter to Comey that was later released to reporters.
