US Constitution, Article 6

A nation can survive its fools and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable for he is known and carries his banners openly. But the traitor moves among those within the gates freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself... for the traitor appears no traitor: He speaks in accents familiar to his victims, and he wears their faces and their garments, he appeals to the baseness that lies deep in the souls of all men. He rots the soul of a nation; he works secretly and unknown in the night to undermine the pillars of the city; he infects the body politic so that it can no longer resist. A murderer is to be less feared. — Cicero
