Definition for expressed powers

The powers are specifically wrote into the constitution and have to be followed and if not it would be unconstitutional

There are three branches in the U.S. government: the legislative branch (Congress, described in Article I), theexecutive branch (the President, described in Article II), and the judicial branch(the Supreme Court and federal court system, described in Article III). Though each of the branches has their own specific powers and duties, it's really the Congress that has the most clearly expressed powers, seeing as how the Framers of the Constitution thought that institution was going to be the most powerful.
