A top National Security Council (NSC) official was forced to leave the group on Thursday, the most recent departure since national security adviser John Bolton joined the administration earlier this year, Politico reports.

Jennifer Arangio, a senior director in the NSC who worked with global groups, was escorted off White House premises and told that she was no longer needed in the administration, according to Politico.

An NSC spokesman told the newspaper that the group doesn’t comment on personnel issues, and Arangio didn’t return the publication’s request for comment.

"She has fought to correct misleading information about refugees and migrants provided to the president by Miller and the DPC," the former White House official said.

The publication also reported that two other top NSC officials, Joel Rayburn and Michael Bell, left the group’s Middle East sector this week.

Rayburn is expected to join the State Department while it’s unclear what the other official, Michael Bell, will do, according to Politico. Rayburn didn't return the publication's request for comment and Bell couldn't be reached.

Several officials have left the NSC since Bolton began officially overseeing the group in early April. Former homeland security adviser Tom Bossert and spokesman Michael Anton are among the officials who have left the NSC.

Bolton has said that he wants to reshape the council.
