Republican presidential nominee Donald Trump announced major shakeups to his campaign Wednesday, bringing on Stephen Bannon as CEO of the campaign and promoting Kellyanne Conway to campaign manager. So who exactly are these new names in the Trump inner circle?

Stephen Bannon

Bannon comes to the Trump campaign after serving as an executive at Breitbart News, a conservative news site and blog. Although new to presidential campaigns, Bannon is set "to bolster the business-like approach of Mr. Trump's campaign," Trump's camp said in a statement.

Bannon served as a Naval officer before starting his career at Goldman Sachs and eventually founding his own investment bank with fellow Goldman colleagues.

In 1999, Bannon turned his attention to Hollywood, serving as a co-executive producer on Academy Award nominated Titus.

Shortly after, Bannon began focusing his film making efforts to politics. In 2004, he wrote and directed In the Face of Evil: Reagan's War in Word and Deed, a documentary about Reagan's crusade against communism, and in 2010 Battle for America, a documentary detailing the frustrations many Tea Party supporters felt during its rise.

"What turned me against the whole establishment was coming back from running companies in Asia in 2008 and seeing that Bush had f---ed up as badly as Carter. The whole country was a disaster,” Bannon told Bloomberg in 2015.

Bannon continued his pro-Tea Party filmmaking in 2011 with a documentary portraying the life and political rise of Sarah Palin.

Bannon has also written extensively in Breitbart blasting the "mainstream media" and defending Fox News. Recently, Bannon wrote about a liberal "plot" to take down Roger Ailes.

"I think it’s virtually the whole of the Democratic establishment, including the Obamas, the Clintons, and their billionaire financiers, such as George Soros. These are the people who are plotting to take down Ailes. And if Ailes goes, I’m afraid, so could America," Bannon wrote.

Trump revamps his team and message, but is it too late?

Kellyanne Conway

Conway brings her pollster and strategist background to the Trump camp and already serves as an adviser to the campaign. Promoting her to campaign manager will allow her to work more closely on messaging and traveling with Trump, according to the campaign's statement.

Conway began her career as a lawyer before getting involved in polling. In 1995, she founded her own polling company, the Polling Company, Inc./WomanTrend, a group that boasts its privately held and women-owned status.

Conway is no stranger to campaigning either. She's worked on campaigns for Vice President Dan Quayle, Speaker Newt Gingrich, Sen. Ted Cruz and even Gov. Mike Pence.

Like Bannon, she has also spoken out again news outlets' treatment of Trump and conservatives.

Conway has recently appeared on many news programs on behalf of the Trump campaign and recently told Time she thinks Trump will be better for American women than Hillary Clinton.
