President-elect Donald Trump has a lot of key positions to fill in the coming weeks that will shape his next four years in office.

While rumors have been flying around about who he will appoint, Trump has so far only made two official hires.

We'll update this list as he announces more senior leadership positions, but here's what we know so far:

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.

Obama administration counterpart: Valerie Jarrett

Former jobs: chairman of the alt-right news site Breitbart, CEO/chief strategist of the Trump campaign

Bio: Bannon, 62, graduated from Harvard Business School in 1983, and made much of his fortune as a Goldman Sachs banker and a longtime movie and TV producer. Since 2011, he has led Breitbart News, the far-right website espousing anti-establishment white nationalist positions, particularly on issues like immigration and trade. Bannon has two 21-year-old daughters, whose mother accused him of domestic abuse and anti-Semitic comments during their divorce proceedings in 1996. He pleaded not-guilty, and the charges were dropped. He has another ex-wife, as well.

Reactions: Bannon's appointment set off a firestorm of controversy, with critics pointing to what they considered racially charged, bigoted rhetoric used on Breitbart under Bannon's leadership.
