First Amendment to the Constitution guarantees the Right of the People to assemble peaceably and part of these inherent and inalienable liberties include the freedom of association.

This directly violates the Right of the People to associate as they see fit, and undermines the balance of Power between the States and individuals, and the Federal Government.

The Bill of (individual) Rights specifically prohibits the Federal and State Government from violation of enumerated Rights of the People, and prevents the curtailing of liberties enjoyed by the People as individuals and private parties to the nation.

This is essentially a Power grab by the Federal branch, officially subverting the Supreme law of the land under the pretence of security.
