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

It’s unclear how the change came about. Reports from The New York Times suggest the President had told senior leaders he wanted Bannon out, but the big question was when and how. However, a person close to Bannon told the news outlet the strategist had submitted his resignation several weeks ago.

The White House has not commented on those statements.

When asked earlier this week if he confidence in Bannon, President Trump replied, “Well, we’ll see… Look, look, I like Mr. Bannon,” Mr. Trump said. “He is a friend of mine. Mr. Bannon came on very late. You know that. I went through 17 senators, governors and I won all the primaries. Mr. Bannon came on very much later than that. And I like him. He is a good man. He is not a racist. I can tell you that. He is a good person. He actually gets a very unfair press in that regard. We’ll see what happens with Mr. Bannon. He is a good person and I think the press treats him frankly very unfairly.”
