 The vice president would become a temporary acting president immediately, but to make it a solidified situation for the vice president to be acting president, it'd have to be a vote of Congress. So even there, the 25th Amendment is not an easy process, but I believe that this is exactly the time in which it should be discussed seriously by both political parties. This is a responsibility of the vice president and the cabinet. The vice president, we a lot of times say, does not have many responsibilities.
