President Trump's chief strategist Steve Bannon is leaving the White House.
The former Breitbart News publisher has had a roller coaster ride in both the Trump campaign and the Administration, facing criticism from establishment Republicans and civil rights groups over his economic nationalism and ties to the alt-right.
Here's a timeline of Bannon's highs and lows with Trump.
July 12, 2015: Bannon calls Trump's book, "Time to Get Tough," a "blockbuster policy manifesto" in a review on Breitbart. Trump tweets a link to the story.
July 21: Trump tweets approvingly of a Breitbart story criticizing NBC News. "Thanks to Steve Bannon and real reporters," he writes.
Nov. 2: Bannon interviews Trump for a Breitbart radio show. In the interview, Bannon says he is concerned that many CEOs in Silicon Valley are from Asia. "A country is more than an economy. We're a civic society," he says.

Feb. 18, 2016: Bannon interviews Trump for a third time.

Nov. 13: Trump names Bannon as chief strategist for his administration, simultaneously tapping Republican National Committee head Reince Priebus as chief of staff. Anti-discrimination groups criticize the Bannon pick.
Nov. 15: Senate Majority Leader Harry Reid criticizes Bannon in a speech on the Senate floor. "By placing a champion of white supremacists a step away from the Oval Office, what message does Trump send to the young girl who woke up Wednesday afraid to be a woman of color in America?" he asks.
Nov. 18: In an interview with the Hollywood Reporter, Bannon says he doesn't mind his public image. "Darkness is good," he says. "Dick Cheney. Darth Vader. Satan. That's power."
Jan. 20, 2017: Trump is inaugurated as the 45th president. "The forgotten men and women of our country will be forgotten no longer," he says in an inaugural address that Bannon reportedly helped write.
Jan. 27: Trump signs an executive order barring travel from seven Muslim-majority countries. Huge protests spring up at U.S. airports. Reporter Joshua Green later writes that Bannon arranged the timing on a Friday afternoon to spur the protests, which he thought would also galvanize Trump voters who supported the president's move.
Jan. 28: Trump adds Bannon to the National Security Council's principals committee, the top interagency group on national security. The move is considered unusual because political strategists have not served on the committee previously.
Feb. 13: Bannon makes the cover of TIME Magazine under he headline "The Great Manipulator." Inside, the cover story asks "Is Steve Bannon the Second Most Powerful Man in the World?"

July 26: Reports surface that Bannon is calling for a top marginal tax rate of 44% on the wealthiest Americans, a break with other Republicans and even with Trump's own proposed tax plan. The idea goes nowhere.

Aug. 15: Asked about Bannon's future in the White House at a press conference, Trump says "we'll see what happens with Mr. Bannon," adding that he is a "good man" and "not a racist" but again noting that he came on to the campaign late.
Aug. 16: In an interview with the progressive American Prospect magazine, Bannon calls white supremacists "a collection of clowns," argues that an "economic war with China" has already begun and says there is no military solution to the North Korea problem.
