US President-elect Donald Trump named his campaign manager, Susie Wiles, as White House chief of staff on Thursday, his first major appointment since winning this week’s election.

“Susie is tough, smart, innovative, and is universally admired and respected,” Trump said in a statement. “Susie will continue to work tirelessly to Make America Great Again. It is a well deserved honor to have Susie as the first-ever female Chief of Staff in United States history.”

Trump went through four chiefs of staff — including one who served in an acting capacity for a year — during his first administration, part of record-setting personnel churn in his administration

Wiles, 67, a Florida native is credited with running a more disciplined campaign operation than Trump’s first run.

She appeared with Trump on stage at his election night victory celebration, but chose not to speak, being the only one not to do so.

She is the daughter of late sportscaster Pat Summerall.
