Question: is the president of the senate the vice president

Answer: Yes, The Vice President of the United States of America (informally referred to as VPOTUS, or Veep) is the second-highest officer in the executive branch of the U.S. federal government, after the President of the United States, and ranks first in the presidential line of succession. The vice president is also an officer in the legislative branch, as President of the Senate. In this capacity, the vice president presides over Senate deliberations (or delegates this task to a member of the Senate), but may only vote to break a tie. The Vice President also presides over joint sessions of Congress.
