Rep. Michele Bachmann grilled Treasury Secretary Timothy Geithner and Fed Chairman Ben Bernanke on Tuesday afternoon about the U.S. Constitution. Bachmann seemed unclear about Congress’ duties under the Constitution.

Bachmann: “What provision in the Constitution could you point to to give authority for the actions that have been taken by the Treasury since March of ‘08?”

Geithner: “Well, the Congress legislated in the Emergency Economic Stabilization Act a range of very important new authorities.”

Bachmann: “What in the Constitution could you point to to give authority to the Treasury’s extraordinary actions that have been taken?”

Geithner: “Every action that the Treasury and the Fed and the FDIC has been using authority granted by this body, the Congress.”

Bachmann: “In the Constitution, what could you point to?”

Geithner: “Under the laws of the land, of course.”

Geithner and Fed Chairman Bernanke’s answers were simple: The Constitution in Article I, Section I grants Congress the right to legislate, and the TARP funds were legislated to give authority to the Treasury.

Bachmann also asked if the United States was giving up the dollar. “I’m wondering would you categorically renounce the United States moving away from the dollar and going to a global currency as suggested this morning by China and also by Russia, Mr. Secretary?”

Geithner and Bernanke: Of course.
