Susie Wiles: Who is Trump's new chief of staff?

US President-elect Donald Trump has announced his campaign manager, Susan Summerall Wiles, will serve as his White House chief of staff when he takes over the presidency next year.

In a statement, Trump said that Wiles "just helped me achieve one of the greatest political victories in American history" and "is tough, smart, innovative, and is universally admired and respected".

"It is a well deserved honour to have Susie as the first-ever female chief of staff in United States history," he continued. "I have no doubt that she will make our country proud.”

Wiles, 67, is the first woman to be appointed White House chief of staff.

The Trump transition team is currently working to choose top members of the incoming Republican administration, including the heads of all 15 executive departments, such as the secretaries of state and defence, from 20 January.

In his victory speech this week, Trump referred to Wiles as "the ice maiden" as she stood behind him on stage.

She operates mostly “in the back”, the president-elect said, but she is known as one of the most feared political operatives in the US.

"Susie will continue to work tirelessly to Make America Great Again," he added in his statement on Thursday, referring to his oft-repeated campaign slogan.

A profile by Politico earlier this year described Susie Wiles as feared but little known.

Less than a year after Wiles started working in politics, she joined Ronald Reagan’s campaign ahead of his 1980 election.

She went on to play a key role in transforming politics in Florida, where she lives.

In 2010, she turned Rick Scott, a then-businessman with little political experience, into Florida’s governor in just seven months. Scott is now a US senator.

Wiles met Trump during the 2015 Republican presidential primary and became the co-chair of his Florida campaign. He went on to win the state over Hillary Clinton in 2016.

Florida Gov Ron DeSantis, who put her in charge of his successful gubernatorial race two years later, described Wiles as “the best in the business”.

Wiles worked on the Trump campaign alongside Chris LaCivita, a veteran of Republican politics with decades of experience.

The two worked with Trump to formulate a winning presidential primary strategy.

In her Politico profile, the 67-year-old grandmother - who is the daughter of late American football player and broadcaster Pat Summerall - said that she comes from a "traditional" political background.

“In my early career things like manners mattered and there was an expected level of decorum," she said, describing the Republican party as significantly different than the one of several decades ago.

"And so I get it that the GOP of today is different," she said, referring to the Republican party, who are also called the Grand Old Party (GOP).

"There are changes we must live with in order to get done the things we’re trying to do."

The chief of staff is considered to be the president's top aide, and plays a crucial role in every president's administration.

They essentially serve as the manager of the White House and are responsible for putting together a president's staff. A chief leads the staff through the Executive Office of the President and oversees all daily operations and staff activities.

They also advise presidents on policy issues and are responsible for directing and overseeing policy development.
