Step-by-step explanation:
The symbol that the vice-president has at his/her station is the Seal of the United States President. This seal symbolizes the authority of the U.S. presidency and represents the power and influence that the office holds over the operation of the United States Government.
The Vice President of the United States also has the role of presiding over the senate, and in the case of a tie vote, they have the opportunity to cast a tie-breaking vote.
