Has the use and perhaps abuse of the informal powers created an "Imperial Presidency?" Defend your answer

The imperial presidency is a fact where the abuse of a power by a president makes it seem like an autocratic rule.

Explanation:

Imperial presidency is something that has happened more often than not in the nation in the times of conflict.

The power of the president is risen up in the time of a war or a major crisis and they are ultimately responsible for a lot of informal decisions that are never taken to court for not following the producer of law as there is an innate understanding on it in the wings of the government.

There are times when it is simply more viable to let the President make the decisions without following protocols but it is a murky territory.
