Also, the president-elect's name is typically added after the "I", for example, "I, George Washington, do..." Normally, the chief justice of the United States administers the oath. It is sometimes asserted that the oath bestows upon the president the power to do whatever is necessary to "preserve, protect and defend the Constitution." Andrew Jackson, while vetoing an Act for the renewal of the charter of the national bank, implied that the president could refuse to execute statutes that he felt were unconstitutional. In suspending the privilege of the writ of "habeas corpus", President Abraham Lincoln claimed that he acted according to the oath. His action was challenged in court and overturned by the U.S. Circuit Court in Maryland (led by Chief Justice Roger B. Taney) in "Ex Parte Merryman", 17 F. Cas. 144 (C.C.D. Md. 1861). Lincoln ignored Taney's order. Finally, Andrew Johnson's counsel referred to the theory during his impeachment trial. Otherwise, few have seriously asserted that the oath augments the president's powers.
