Another power to add to the list would be: Deciding the legality of executive orders.
An example would be Executive Order 13769, which was titled, "Protecting the Nation from Foreign Terrorist Entry into the United States." President Donald Trump signed this order on January 27, 2017, in the first weeks of his presidency.
