Which of the following is NOT a power that the Constitution gives the Vice President? Presides over the Senate.
Assumes the role of President if he/she is unable to hold office.
Casts the deciding vote if the Senate is deadlocked with a tie.
Determine if a law passed by Congress is unconstitutional.

Clarification:

The Constitution gives the Vice President the right to preside over the Senate. They are the President of the Senate, and therefore they can also cast a deciding vote in a Senate case. They also are the Vice President, which means they will be in charge of the White House after the President is unable to hold his/her office.

The Constitution does not allow the Vice President to determine if a law passed by Congress is unconstitutional. The state, federal, and Supreme Courts look into unconstitutional things. The Vice President does not have authority over determining if a law passed by Congress is unconstitutional. The Judicial Branch holds this matter. Our answer is determine if a law passed by Congress is unconstitutional.
