Another Republican president, George H.W. Bush, named three White House chiefs of staff during his one term in office: John Sununu in 1989-91, Samuel Skinner in 1991-92 and James Baker in 1992-93.

Donald Trump announced his first staffing choices for his administration Thursday, naming longtime Republican political operative Susie Wiles, who worked on all three of his presidential campaigns, as his White House chief of staff.

After helping engineer Donald Trump’s improbable and sweeping victory in the presidential race, Susie Wiles, the president-elect’s unassuming co-campaign chief, is seen as the frontrunner to become his White House chief of staff, according to six sources familiar with discussions inside the campaign.
