Let the Constitution be our guide. If it is not specifically provided for in the Constitution, then it must be defunded, disbanded, and never allowed to return. CIA, FBI, ATF, IRS, EPA, OSHA, Dept of Education, USCP, ONDCP, OFL, USDA, NOAA, National intelligence agencies, Department of Energy, Department of Health and Human Services, FEMA, Department of Housing and Urban Development, Department of the Interior, Department of Justice (Huge reduction, return to the original intent), Department of Labor, Department of State (Huge reduction, return to the original intent), Department of Transportation (Reduce to just coordinating Interstates, Railroad, etc for inter-state commerce), Department of the Treasury (Huge reduction, return to the original intent), EEOC, National Council on Disability, most Independent agencies, tribunals, and government-owned corporations. and all Quasi-official agencies. Any other federal government operation not specifically provided for in the Constitution.

Let's also tackle some other unconstitutional practices that have become customary:

1. All Legislative Bills must be for a single item. No more multiple item, complex bills.
2. No more "delegation" of power or authority of any elected office. For example, Congress cannot delegate any of its duties to any other entity or person.
3. All Legislative Bills MUST be easily read and understood my the common man. No more legalese, or complexities intended to confuse the common man.
4. Repeal all Amendments that cannot be definitively proven to have been properly ratified, or that go against the original intent of the framers of the Constitution (16th amendment, 17th amendment, and 23rd Amendment)
5. Propose “Titles of Nobility Amendment” (or TONA) to ban any American citizen from receiving any foreign title of nobility or receiving foreign favors, such as a pension, without congressional approval. The penalty being loss of citizenship.
6. Anchor babies. The Civil Rights Act of 1866 had granted citizenship to all people born in the United States if they were not subject to a foreign power, and this clause of the Fourteenth Amendment constitutionalized this rule. All illegal immigrants are subject to a foreign power by virtue of being citizens of a foreign country. Time to enforce that, and roll back citizenship to everyone granted it under false pretenses.
7. Pass an amendment that requires proof of citizenship and identity to vote, and requires paper ballots with serial numbers to secure all federal elections. No electronic voting machines, not multiple day vote counts, and not cheating of any type allowed.
