The Constitution grants the Congress the power to control the currency. The Federal Reserve is a private entity that is granted the power to create money and charges the government for the favor.
Majorities on the left and right and in the center alike agree that the Federal Reserve is a corporate cartel that is usurping constitutional powers reserved to the people. The government should take back the power to create money and credit from the Wall Street banks that ran the economy into the ground by terminating the statutory entitlement of Federal Reserve Bank.
