 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 the responsibility of the Vice President and the Cabinet. The Vice President, we a lot of times say, does not have many responsibilities.
