WASHINGTON — Dina H. Powell, a deputy national security adviser to President Trump and a key player on a variety of foreign policy issues since the early days of his administration, will step down early next year, the White House said on Friday.
In a White House riven by tribal divisions, Ms. Powell has been a prominent member of the camp affiliated with Ivanka Trump and Jared Kushner. Her departure will remove one of the figures who has resisted some of the more provocative policies advocated by the wing associated with Stephen K. Bannon, the nationalist who stepped down over the summer as the president’s chief strategist.
Her influence extended at times beyond the national security issues that normally would be under her purview, and her name was floated at points as a potential White House chief of staff. But her family had remained in New York while she worked at the White House and friends have said the job and the struggles within the West Wing have worn on her.
“Dina Powell has been a key, trusted adviser in this administration,” said the press secretary, Sarah Huckabee Sanders. “She has always planned to serve one year before returning home to New York, where she will continue to support the president’s agenda and work on Middle East policy. She will serve in the administration until early next year.”
