Establishing a fourth branch of govt, could that be treasonous

Read a lot in the past 4 days about how the government works not the way civics is taught with 3 branches, president , congress, and Supreme Court .

Best discussions indicate the fbi,cis,nsa,justice group was brought together after 9/11 to provide enhanced communication. pundits believe the Obama admin used the closer working relationship to establish an unelected political organization to oversee the congress, president, courts. Thie fourth leg of the govt has the resources to gather info on every person in the us, and used the info to threaten politicians for compliance.

Are the folks that set up this fourth branch without following constitution, guilty of treason for changing without involvement of the voter
