Powers exclusively held by congress?
The powers that are exclusively held by congress include ability to change taxes, impeach the president and declare war. These powers are expressed by the constitution.
The People of this land have allowed Congress to gain more and more powers over them year after year! Because the People never require Congress to be held accountable for their actions, and never require Congressmen to obey the laws of the land, and never stop Congressmen from usurping powers that were never theirs.
Delegated Powers are powers given only to the federal government. Reserved Powers are powers reserved for state governments. and concurrent powers are powers shared between the state and federal governments. Implied powers are powers that congress are not specifically listed in the constitution and expressed powers are powers of congress that are specified.
Why did the constitution specifically describe the powers of the Congress but remain vague about the powers of the president?
The Constitution's division of powers leaves the President with some exclusive powers as Commander-in-Chief, Congress with certain other exclusive powers, and a sort of "twilight zone" of concurrent powers. Congress also has the power to limit the powers of the President. The Constitution describes the powers of Congress more than those of the president because initially Congress was supposed to rule the country while the president didn't do much.
