TETERBORO, N.J. -- Donald Trump announced a shake-up of his campaign leadership Wednesday, the latest sign of tumult for his struggling White House bid less than three months from his Election Day faceoff with Hillary Clinton.
The Republican nominee named Stephen Bannon of the conservative Breitbart News website as chief executive officer and promoted pollster Kellyanne Conway to campaign manager. The moves signal that Trump plans to embrace his populist, outsider persona in the campaign's final stretch rather than moderate and extend a hand to more traditional Republicans.
"I've known both of them for a long time. They're terrific people, they're winners, they're champs, and we need to win it," Trump told The Associated Press in a phone interview in the early hours of Wednesday morning.
Paul Manafort, Trump's controversial campaign chairman, will retain his title. But in announcing the shakeup, Trump said Bannon would now oversee the campaign staff and operations, raising questions about Manafort's role going forward.
Manafort has spent months trying to ingratiate Trump to Republican lawmakers who have urged the billionaire businessman to dial back his fiery rhetoric and run a more traditional campaign. Trump has largely resisted those pleas and the latest staff changes appear to be a rejection of Manafort's attempt to tame Trump.
Bannon's website has been a cheerleader for Trump's campaign for months and also critical of Republican leaders, including House Speaker Paul Ryan. A former Goldman Sachs banker, Bannon does not have presidential campaign experience but he shares Trump's combative approach to politics.
Conway joined Trump's campaign earlier this year as a senior adviser. A longtime Republican strategist and pollster, she has close ties to Trump's running mate, Indiana Gov. Mike Pence.
Speaking to reporters at Trump Tower on Wednesday, Conway called the changes "an expansion" at "an incredibly busy time going into the last 12-week home stretch for the campaign, and we look at personnel as more is more."
She described herself, Bannon, Manafort and his deputy Rick Gates, who has been travelling often with Trump and is expected to retain a senior role, as the "core four."
Manafort, who took over the reins following the departure of campaign manager Corey Lewandowski in June, has come under scrutiny because of his past work for a pro-Russian Ukrainian political party. The Associated Press reported Wednesday that Manafort helped the party secretly route at least $2.2 million in payments to two prominent Washington lobbying firms in 2012, doing so in a way that effectively obscured the party's efforts to influence U.S. policy. Gates, who had worked with Manafort on Ukrainian issues, told the AP he and Manafort had consulted with the lobbying firms on Ukrainian politics, but called the actions lawful.
The campaign shake-up, first reported by the Wall Street Journal, comes as polls show Trump trailing Clinton nationally and in key battleground states following a difficult campaign stretch that saw him insulting the Muslim parents of a U.S. Army soldier who died in Iraq and temporarily refraining from endorsing Ryan in his Wisconsin primary race.
While Trump's campaign staff publicly insists there is plenty of time left for the Republican to change the trajectory of the race, the candidate is facing a shrinking timeline. Early voting begins in a handful of states in September.
A source familiar with the candidate's thinking said Trump has become increasing frustrated by the grim poll numbers, his advisors' attempts to moderate his style and what he views as disloyalty from Republicans who failed to come to his aid. The candidate believes he can right his campaign by being himself, keeping up a schedule of red-meat-filled rallies, and being more aggressive on the stump, said the source, who was not authorized to speak about campaign conversations publicly.
Supporters in the "let Trump be Trump" camp heralded the moves.
The addition of Bannon and Conway mark "a great day for Donald Trump because he can now be free to continue speaking truth to power," said David Bossie, the leader of a pro-Trump super PAC. "He believes he should stay true to what got him this far. It's essentially, 'dance with the one who brung ya."'
Clinton dismissed the new leadership as meaningless.
"I think it's fair to say that Donald Trump has shown us who he is. He can hire and fire anyone he wants from his campaign, they can make him read new words from a teleprompter, but he is still the same man," she said on the stump in Cleveland. "There is no new Donald Trump. This is it."
Details of the new pecking order were hashed out at a lengthy senior staff meeting at Trump Tower Tuesday while the candidate was on the road. A statement announcing the hires was released Wednesday. Additional senior hires are expected soon.
Both Bannon and Conway have close ties to Republican megadonor Robert Mercer, who leads a New York hedge fund and has investments in Breitbart News. Mercer also put $13.5 million into a super PAC Conway ran during the Republican primary in support of Texas Sen. Ted Cruz.
Mercer has authorized the pro-Cruz super PAC to begin doing work to help Trump. Super PACs are organizations that can raise and spend unlimited amounts of money to support a candidate, but can't co-ordinate with the candidate's campaign.
Trump's own campaign has enjoyed a burst of fundraising from direct mail and online donations, saying it raised $64 million that way in July alone -- the vast majority of which goes to his campaign, not the Republican Party.
Although Trump has repeatedly said he plans to lean on the party to pay for key operations such as voter door-knocking, it is increasingly clear that he will have the money to build on his own if he chooses to do so.
The campaign announced Tuesday that it would finally begin airing its first ads of the general election next week in the battleground states of Florida, Ohio, North Carolina and Pennsylvania.
