What is the primary responsibility of the Vice President of the United States?

The primary responsibility of the Vice President of the United States is to serve as President of the Senate. In this role, the Vice President has the authority to preside over Senate sessions, which includes maintaining order and decorum, recognizing speakers, and overseeing the legislative process. Additionally, the Vice President has a crucial function in breaking ties in the Senate, ensuring that this legislative body can continue to function effectively.

While other functions may be associated with the Vice Presidency, such as being a key advisor to the President or stepping in as acting President if necessary, the official constitutionally defined role that distinguishes the Vice President within the legislative branch is the position of President of the Senate. This role highlights the Vice President’s connection to the legislative process, as opposed to the broader responsibilities associated with the executive branch or the judiciary.
