Briefly explain the role the president, congress, and federal courts in passing and carrying out the laws of the United States.

Passing of laws is done by the Congress and the bills should pass both the House of Representatives and the Senate before in can be sent to the President.

The President is the leader of the executive branch and can either veto or sign a bill. The bill will become a law if signed and the bill will not become a low if vetoed. However, if 2/3 of each house votes in favor of the override, Congress can bypass the Presidential veto. Enforcing the law is the executive branch's responsibility.

Laws that are unconstitutional are what the federal courts must protect against its people. The people can take the law to court if they feel that a law that is passed is unconstitutional and federal judges will either uphold or strike the law down based on the ruling of the law's constitutionality. The Supreme Court has the final say regarding a law's constitutionality.
