The confirmation hearings for President-elect Donald Trump's cabinet picks are set to be some of the most controversial in living memory. No incoming administration has seen one of its nominees rejected by a same-party Senate since 1925, and because of Senate Democrats' resort to the "nuclear option" in 2013, most executive nominations can pass with a simple majority.

Even so, a couple of Trump's nominees are facing a tough confirmation process: speculation is swirling that Republican senators such as Marco Rubio and John McCain could deny Exxon Mobil Corp. (XOM) CEO Rex Tillerson the job of Secretary of State due to the nominee's close ties to Russian leaders, including President Vladimir Putin. Alabama Senator and nominee for Attorney General Jeff Sessions had to pause during his remarks on the morning of January 10 as protestors' cries of "no Trump, no KKK, no fascist USA" and "you're a pig" echoed through the Senate chamber.

Even those whose confirmation prospects are relatively certain – including Sessions – face a potentially grueling process as Democrats register their bitter opposition not just to the nominees, but to their soon-to-be boss.  

Questions have also been raised regarding missing documentation for some nominees. The Senate moved Betsy DeVos' first hearing, originally scheduled for January 11 at 10:00 a.m., to January 17 because the Office of Government Ethics has not yet completed its review of the nominee for Secretary of Education. Walter Shaub Jr., the head of the federal watchdog, wrote a letter to Democratic senators on January 13 describing the "undue pressure" his office was under to proceed with the hearings despite incomplete ethics reviews. In a press conference on January 11, Trump dodged questions about potential conflicts of interest in his cabinet, calling the nominees "brilliant."

Below is the schedule for confirmation votes, along with the results where applicable:

Date Nominee Position Result Vote
Jan 20 James Mattis Secretary of Defense Confirmed 98-1
Jan 20 John Kelly Secretary of Homeland Security Confirmed 88-11
Jan 23 Mike Pompeo CIA Director Confirmed 66-32
