Trump and His Cabinet Explained

Trump's cabinet is one aspect of a very controversial presidency. This thread is mainly to go over the process of nomination and to discuss his nominees. I'll also link a video that explains how it's done--if you don't want to read all this text:

First of all, the US Cabinet is not actually mentioned in the constitution, but is instead based off of this line from Article 2, Section 2, Clause 2: "...and by and with the Advice and Consent of the Senate, shall appoint Ambassadors, other public Ministers and Consuls, Judges of the supreme Court, and all other Officers of the United States,"

Now, in the UK, the Cabinet can be appointed very quickly and is a pain to remove. The opposite can be said for the US. Pain to appoint, easy to remove.
For example, it took Trump's first ever Cabinet in 2017 97 days to be fully approved, and the way things are headed, history is set to repeat itself.
It is important to note that Cabinet nominations are not usually controversial, so we shall discuss the standouts from the Trump era(s): Pete Hegseth, Matt Gaetz, Betsy DeVos, RFK and Kash Patel.

First of all: Nominations.
Nomination to the Cabinet is great, but it comes with a lot of background checks. Hegseth was interrogated by the FBI for the post of Defence Secretary--and the Senate has the power to gather witnesses to argue why you should be appointed, and why you shouldn't be appointed. This is where controversy can emerge, as around this time Matt Gaetz, Trump's initial pick for attorney general, was facing various claims of sexual misconduct, with a report from Congress to be released to the public. This report and the controversy surrounding him led to him rescinding his nomination.

The Hearing: The nominee is placed in front of the appropriate Senate Committee. For example, RFK found himself in front of the Health Committee.
Hearings can also last a few days, and the time gap between voting and questioning can be also be a few days.

Voting: The entire Senate votes on if the nominee can be appointed, won by a simple majority.

Controversial nominees:
Betsy DeVos, Education Secretary
Why?: From the family that often donated to the Republican party, she campaigned for Trump. Grilled for her little experience in the field of education. Was appointed by a tie-breaking vote.

Robert F. Kennedy, Health Secretary
Why?: Often promoted anti vaccine policies, has gone on record to say that if he could time travel, he'd stop his children from getting vaccinated. Argued that black people should be on a different vaccination policy than white people, due to their "superior immune systems." Confirmation TBA.

Pete Hegseth, Defence Secretary
Why?: No real military experience outside of the national guard. One senator actually said to his face he did not think he was qualified. Appointed to the Cabinet via tie-breaking vote.

Kash Patel, Director of the FBI
Why?: Said that January 6th was 'not a riot.' Refused to acknowledge the results of the 2020 election. One of many.
