Answer:
<h2>
Senate </h2>
Explanation:
The second article of Section 2 of US constitution says that president should nominate the ambassador, public consuls , public ministers and other officers of US.
The appointment clause allows the president to appoint the cabinet officers. Senate controls the appointment process and the rules for nomination vote to get to the Senate floor.
If the Senate is not in session then the president can appoint officers directly without using recess appointment powers.
The 23rd amendment granted the District of Columbia the right to vote. The amendment granted access to Electoral votes as if it were a state.
It is the Chief Justice.
You can do all of this by elimination.
The Secretary of State and the Attorney General are both department heads, and the Vice President is most likely going to be in the cabinet as well.
Hope this helps!!!
