Congreso de la Nación (in Spanish)

The Congress of the Argentine Nation is the legislative branch of the government of Argentina. It has two parts. There is a 72-seat Senate and a 257-seat Chamber of Deputies.

The Congress is in charge of setting taxes and customs. These must be the same across the country. It rules the Central Bank of Argentina, manages internal and external debt payment, and the value of national currency (currently the Argentine peso). view more...
