Obama administration counterparts: Rahm Emanuel, Pete Rouse, Bill Daley, Jack Lew, Denis McDonough (current)
Former job: Chairman of the Republican National Committee
Bio: Priebus, 44, got his law degree from the University of Miami in 1998. He worked his way up through the ranks of the Republican Party, becoming the Wisconsin Party Chairman in 2007, then general counsel to the National Committee in 2009, and finally its chairman in 2011. Priebus helped launch Wisconsinites House Speaker Paul Ryan and Gov. Scott Walker to national prominence over the last several years. He has two young children with his wife, Sally.
Reactions: While Priebus' hire may comfort the Republican establishment, it may aggravate some of Trump's supporters who expect him to fulfill his promise to "drain the swamp" of Washington insiders in government.
