Susie Wiles, a longtime GOP operative, will serve as President-elect Donald Trump's White House chief of staff.

Wiles, who has largely stayed out of the spotlight, is widely praised for leading Trump's most disciplined and well-executed campaign.

During his victory celebration in West Palm Beach, Florida, Trump specifically thanked Wiles for her outstanding role in the campaign.

“Let me also express my deep appreciation to Susie (Wiles) and Chris (LaCivita) for the work they have done. Susie, come on, Susie,” Trump said. “Susie prefers to stay in the background, I can tell you that. The ice baby. We call her the ice baby. Susie likes to stay in the background. She’s not in the background.”

Trump described Wiles as “tough, smart, innovative” and said she was “universally admired and respected.”

He noted her role as the first female chief of staff in U.S. history and said, “I have no doubt that she will make our country proud.”

Wiles is a longtime Republican strategist from Florida who ran Trump's campaigns in the state in 2016 and 2020. His decades-long political career dates back to his work as a campaign planner for former President Reagan for his 1980 presidential bid.

Wiles also managed Rick Scott's campaign for governor of Florida in 2010 and briefly served as manager of former Utah Governor Jon Huntsman's 2012 presidential campaign.

Wiles currently serves as a senior adviser to Trump and is campaign co-chair alongside Chris LaCivita.

Former House Speaker Kevin McCarthy was previously considered a possible candidate for chief of staff, but recently told “The Guy Benson Show” that he would not accept the position if it were offered to him.

“People always ask me if I'm going to be chief of staff – no, I won't… that's a no,” he said.
