Chief strategist Steve Bannon’s days in the White House are over, sources have told The Associated Press and the New York Times.

The exact nature of his departure has yet to be worked out, according to the Times.

Bannon, 63, has been a key adviser to President Donald Trump’s general election campaign and a forceful but contentious presence in a divided White House.

The former leader of conservative Breitbart News has pushed Trump to follow through with his campaign promises. But he’s also sparred with some of Trump’s closest advisers, sources have told The Associated Press, including son-in-law Jared Kushner.

After serving in the navy, Bannon earned an MBA at Harvard and worked in investment banking. He helped back movies and television, his involvement in the sale of Castle Rock Entertainment earning him a stake in the syndication of Seinfeld and other shows.

After the Sept. 11 attacks, Bannon wrote and produced documentaries based on his belief the West was engaged in a clash of civilizations with radical Islam.

While hosting Trump on his Sirius XM radio show in 2015, he also lamented the presence of foreign-born tech professionals in California.

“When two-thirds or three-quarters of the CEOs in Silicon Valley are from South Asia or from Asia, I think … a country is more than an economy. We’re a civic society,” said Bannon.

Bannon becomes the latest departure amid a number of resignations and firings in the first seven months of the Trump administration. They include:

  • Sally Yates, acting attorney general.
  • Michael Flynn, national security adviser.
  • James Comey, FBI director.
  • Sean Spicer, press secretary.
  • Reince Preibus, chief of staff.
  • Anthony Scaramucci, communications director.
  • Josh Pitcock, vice-president’s chief of staff.
  • Walter Shaub, head of the office on government ethics.
