what role does the vice president of the united states serve in congress
Vice President of the United States As the Senate president, the vice president presides over its deliberations (or delegates this task to a member of the Senate), but is allowed to vote only when it is necessary to break a tie.[3] While this vote-casting prerogative has been exercised chiefly on legislative issues, it has also been used to break ties on the election of Senate officers, as well as on the appointment of Senate committees.[4] In this capacity, the vice president also presides over joint sessions of Congress.[3]
Twenty-fifth Amendment to the United States Constitution Section 4 is the only part of the amendment that has never been invoked.[25] It allows the Vice President, together with a "majority of either the principal officers of the executive departments or of such other body as Congress may by law provide", to declare the President "unable to discharge the powers and duties of his office" by submitting a written declaration to the President pro tempore of the Senate and the Speaker of the House of Representatives. As with Section 3, the Vice President would become Acting President.

Casting vote While having the same right to vote as any member of the House, the Speaker of the United States House of Representatives, to maintain the appearance of impartiality, typically does not vote unless doing so would make a difference. This is, in effect, a casting vote.
