The wording of this clause caused much controversy at the time it was first used. When William Henry Harrison died in office, a debate arose over whether the vice president would become president, or if he would just inherit the powers, thus becoming an acting president. Harrison's vice president, John Tyler, believed that he had the right to become president. However, many senators argued that he only had the right to assume the powers of the presidency long enough to call for a new election. Because the wording of the clause is so vague, it was impossible for either side to prove its point. Tyler took the Oath of Office as president, setting a precedent that made it possible for later vice presidents to ascend to the presidency unchallenged following the president's death. The "Tyler Precedent" established that if the president dies, resigns or is removed from office, the vice president becomes president.
