President Trump's deputy national security adviser, Dina Powell, will leave her post in the administration by early next year, the White House said on Friday.

"Dina Powell has been a key, trusted advisor in this administration. 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," White House press secretary Sarah Sanders said in a statement. "She will serve in the administration until early next year."

Powell took over as deputy national security adviser in March amid the shake-up on Trump's National Security Council that followed after Michael Flynn, former national security adviser, was fired in February. She began her tenure in the administration as an economic aide.

"Dina has been an invaluable member of President Trump's team," national security adviser H.R. McMaster said Friday. "She organized and drove an effort to restore our nation's strategic competence. Dina ensured that our integrated strategies protected the American people and promoted American prosperity. Her sage advice helped provide options to the president and her strong relationships across the U.S. government and internationally helped drive execution of the president's decisions."

McMaster described Powell as "one of the most talented and effective leaders with whom I have ever served."

Jared Kushner, trump's son-in-law and senior adviser, also praised Powell in the White House's announcement of Powell's impending departure.

"Dina has done a great job for the administration and has been a valued member of the Israeli-Palestinian peace team," Kushner said. "She will continue to play a key role in our peace efforts and we will share more details on that in the future."
