Which presidential appointment is the most contentious?

Chief or Associate justice appointments to the Supreme Court of the United States.

Explanation:

When it comes time for a president to appoint an associate or Chief Justice, there is a lot of discussion and debate surrounding it. This is because justices in the Supreme Court have a life tenure, meaning they can hold their office for their entire life.

It is very important who the president decides to appoint because justices are members of the highest court in the federal judiciary branch. They have the ultimate responsibility of interpreting and safeguarding the U.S. Constitution.
