Protesters the Fernandez administration is corrupt.
(SOUNDBITE) (Spanish) PROTESTER, JORGE WARD, SAYING:
"We're protesting because of the deterioration of our institutions and their lack of independence, and against the subjugation of the courts. We have an economy headed by a crazy person. There's no finance ministry to speak of and there's uncertainty in practically every state institution."
The protest comes as the Argentine economy slows down after almost a decade of solid growth.
Mass protests against the economic policies of former President Fernando de la Rua led to the collapse of his government in 2001.
